To help the selective serialiser we can return the original
HTML for generated content if it is unmodified.
As the output of toDomElements now depends on changes
to the dataElement we now have a 'modify' function in
the some test cases.
We also now have 'storeItems' to assert that the index-value
store is correctly populated and for loading values back
into the store for toDomElements tests.
Also make 'mw' an attribute and remove 'about' property.

addSet:
* Instead of indexing items in the store, just union the indexStore arrays
removeSet/removeNotInSet:
* difference or intersect the indexStore arrays
filter:
* push indices into the result set instead of values
simpleArrayUnion/Intersect/Difference have been created as utilities
in ve. They are prefixed 'simple' because they use object keys to
do fast in-array comparisons. This means they are limited to string
values or values which will compare as strings (e.g. numbers).

By removing the transaction listeners from surface fragments we
no longer have to make sure they are always manually destroyed.
In order to retain the functionality of having fragments update
with transactions elsewhere we keep a pointer to a place in the
new complete history stack in the surface. The complete history
stack records all transactions, even undone ones.
Whenever getRange is called we replay all transactions in the
complete history (in the correct order) since the fragment was
last updated.
Also in this commit:
* Updated Format/IndentationAction to test undo(). This increases
coverage of surface fragment behaviour.
* .range is always accessed by .getRange now, although as an
optimisation we can use the noCopy mode when we a sure the
returned range will not be modified.
* Added undo test to .update (previously .onTransact)

This was broken, especially in wrappers.
Changed the wrapping algorithm so that meta items are placed outside
wrappers if possible. On the left-hand side, this is already the case:
we don't open wrappers for meta items. On the right-hand side, this is
accomplished by buffering the meta items and only inserting them when
we encounter either real text (not whitespace) or the end of the wrapper.
If we're interrupted by real text, we insert the meta items with the
unmodified whitespace. If we're interrupted by the end of the wrapper,
we insert the meta items outside of the wrapper with whitespace stripped.
Internally, this is done by stripping the whitespace into the whitespace[0]
of the meta item to its right. Then when we output the meta items, we
either decide to 'restore' the whitespace, or to 'fixup' by also setting
whitespace[3] on the element before the whitespace.

So. It turns out that the design of SurfaceFragment is a little -
shall we say - wonky.
One of the best things about ve.dm.SurfaceFragment is its magical
ability to retain the intention of its range, even as transactions
are being processed. This ability is granted by each fragment
listening to the surface's change event, and responding by using
translateRange for each transaction that gets processed. Surface
fragments also have these clever methods that allow you to get a
fragment based on another, which makes adjusting the range easy to do
inline without having to manually store multiple fragments or
modifying the original.
This sounded good, and we seemed to all be convinced it was well
designed. But if you add a console.log( 'hello' ); to the first line
of ve.dm.SurfaceFragment.prototype.onTransact, and then start using
the bold tool on various selections of text, you will find that there
may indeed be a flaw. What you will probably realize is that the
number of times that particular line of code is being called is
disturbingly large, and increases each time you do just about anything
in the editor. What's going on? How did we get here? Read on…
It turns out that fragments are immortal. We create them, they listen
to the surface's transact event, we are done with them, but the
surface keeps on emitting events to the now long forgotten about
fragments. They continue to build up over time, never go out of scope,
and bloat the hell out of our program.
The same ended up being true of toolbars - and each time the context
menu fired up a new one the old one was left in limbo, still
responding to events, still taking up memory, but not being visible to
the user.
All of this immortality was causing strange and difficult to track
down problems. This patch fixes this by introducing a destroy method.
This method unbinds events, allowing the object to finally fall out of
scope and die - and more importantly stop receiving notifications of
changes.
This is a hack, but Ed will no doubt get this situation sorted out
properly by making fragments lazy-evaluate their selections by only
storing an identifier of the most recent transaction they were based
on, see bug 47343.

Before, it took an array of objects and translated those to indexes
using the store. Literally every caller outside of the test suite got
an array of indexes from the linear model, translated those to objects,
then passed them into the AnnotationSet constructor which translated
them right back to indexes.
The previous behavior was kind of ridiculous on its face, but the
reason we found it is because Inez was investigating the performance
degradation when bolding a line and found that half of it was due
to the hundreds of ve.getHash() calls caused by this behavior.

Context-sensitive nodes are HTML elements like <caption> that can only
appear in certain contexts (<table> in this case). This means that
serializing them by throwing them in a <div> and calling .innerHTML
fails, because the browser knows a <caption> can't be in a <div> and
unwraps it. jQuery's .html() function is clever though and knows to wrap
<caption> in a <table> (and has similar rules for other elements).
So use jQuery's .html() rather than manual .innerHTML stuff.

In HTML like <td>Foo <b>Bar</b></td>, the space would be stripped and
registered as trailing whitespace in the <td>, so it wouldn't be visible
in the editor and would be inserted after the </b> on the way out.
Thanks to Subbu for reporting this. This case was kind of ridiculous and
we're lucky the JRuby article contained it. To trigger the bug, you had
to have:
* a table cell
* containing unwrapped content
* consisting of
** some text
** whitespace
** open annotation (bold in my example, link in Subbu's case)
** text
** close annotation
** and nothing else

The first run of getDomFromData() would preserve whitespace just fine,
but it blanked out the .veInternal.whitespace[1] element in certain
cases, contaminating the linear model and making the whitespace data
inconsistent. Subsequent runs of getDomFromData() would then refuse to
serialize that whitespace because the information about it was
inconsistent.
In getDomFromData(), we sometimes unset .veInternal.whitespace[1] (i.e.
set it to undefined) to prevent double processing. Because we're
potentially going to modify .veInternal, don't assign it by reference,
but copy the object.
Added tests asserting that the linear model is unchanged after calling
getDomFromData(), because that function should never modify
linear model data. This test failed in 4 cases (all whitespace-related)
before I added the copyObject() call.

This changes the annotation API to be the same as the node API, sans
a few boolean flags that don't apply. The APIs were different, but
there was really no good reason why, so this makes things simpler for
API users. It also means we'll be able to factor a bunch of things out
because they're now duplicated between nodes, meta items and annotations.
Linear model annotations are now objects with 'type' and 'attributes'
properties (rather than 'name' and 'data'), for consistency with elements.
They now also contain html/0/* attributes for HTML attribute preservation,
which obsoletes the htmlTagName and htmlAttributes properties.
dm.Annotation subclasses take a reference to such an object and implement
conversion using .static.toDataElement and .static.toDomElements just
like nodes do. The custom .getHash() functions are no longer necessary
because of the way HTML attribute preservation was reimplemented.
CE rendering has been moved out of dm.Annotation (it never made sense to
have CE rendering functions in DM classes, this was bothering me) and into
separate ce.Annotation subclasses. These are very similar to CE nodes in
that they have a this.$ generated based on something in the DM; the main
difference is that nodes listen to events and update themselves, whereas
annotations are static and are simply destroyed and rebuilt when they
change. This change also adds whitelisted HTML attribute rendering for
annotations, as well as class="ve-ce-FooAnnotation" attributes.
Now that annotation classes produce real DOM nodes rather than weird
objects describing HTML tags, we can't generate HTML as a string in
ce.ContentBranchNode anymore. getRenderedContents() has been rewritten
to be much more similar to the way the converter renders annotations;
in fact, significant parts of it were copied from the converter, so that
should be factored out in the future. This change actually fixes an
annotation rendering discrepancy between ce.ContentBranchNode and
dm.Converter; see the diff of ve.ce.ContentBranchNode.test.js.

Using element.height was returning 0 if the attribute was empty
when in fact what we mean to store is null (i.e. auto height).
This takes care of the writing of attributes in CE as jQuery
ignores an attribute-set command if the value is null.
Also in this commit I've implemented a basic toDomElements
that outputs the original HTML (code copied from AlienNode).
This stops the code from throwing an exception but will
eventually need to be rewritten to rebuild the HTML from
the attributes stored in the DM.
