Ran makeStaticLoader.php:
- Synced mis-match of css in demos.
- Added missing experimental.
We originally had experimental in static. They were removed
because the section became empty (not because we no longer
wanted them in static loader). If we don't want them here, we
should remove the entry from makeStaticLoader.php.

In the DomFromData tests, we put the provided storeItems in the store
first, then run preprocessAnnotations (which puts annotations in the
store). However, in DataFromDom we ran preprocessAnnotations first
(which puts annotations in the store), then ran getDataFromDom (which
is expected to put the asserted store items in the store). Because the
order was reversed between these two tests, it was impossible to write
a test for an annotation whose toDataElement function adds to the store.
Fix this by reordering the operations in the DataFromDom test, doing the
conversion first and only then running preprocessAnnotations on the
expected data. This preprocessAnnotations call will not write to the store
if the test passes, because all annotations in the expected data should
already have been put in the store by the conversion.

An empty document is one which contains no 'real' data, so

It was being used correctly in the textual replace case, but it was
omitted in the structural replace case. This caused rare, insidious
metadata placement bugs that I haven't been able to reproduce outside
of newFromDocumentInsertion testing, but this might explain some of
the odd category bugs that have been reported.

Any annotation could have a style attribute which has
a compound effect, and this also prevents roundtrip

This was broken after 92c38ea removed ve-mw files from the
static loaders but didn't update makeStaticLoader.php so
it was harder to keep the files in sync and a few minor issues
on the documentation pages.
Since the files are still mixed in the non-mw modules the only
way to exclude them is to do what was manually done in 92c38ea:
Filter out paths starting with "ve-mw/" from non-mw modules.

Move all MW-specific files into the ve-mw directory, in preparation
for moving them out into a separate repo.
All MW-specific files were moved into a parallel directory structure
in modules/ve-mw . Files with both generic and MW-specific things were
split up. Files in ve/init/mw/ were moved to ve-mw/init/ rather than
ve-mw/init/mw ; they're still named ve.init.mw.* but we should change
that. Some of the test files for core classes had MW-specific test cases,
so those were split up and the test runner was duplicated; we should
refactor our tests to use data providers so we can add cases more easily.
Split files:
* ve.ce.Node.css
* ve.ce.ContentBranchNode.test.js (MWEntityNode)
* ve.ce.Document.test.js (some core test cases genericized)
* ve.dm.InternalList.test.js (uses mwReference test document)
* ve.dm.SurfaceFragment.test.js, ve.ui.FormatAction.test.js
** Made core tests use heading instead of mwHeading
** Updated core tests because normal headings don't break out of lists
** Moved test runners into ve.test.utils.js

We currently change <ref name="foo">Foo</ref> ... <ref name="foo">Foo</ref>

that the second ref tag isn't canonical and so we blank it.
Instead, we now preserve the contents of all ref tags that come after
the canonical one.

The converter wasn't setting .annotations on meta items created to
represent empty annotations, which meant that HTML like
<i>Foo<b></b></i> would end up as <i>Foo</i><b></b> in the linmod.
Change-Id: I13d7d9820beeee1e8c3673e08051361d6c6ac4cd
If you had <meta /><b>Annotated text</b> in a wrapper paragraph,
the converter would swap them and output the linear model equivalent
of <p wrapper><b>Annotated text</b></p><meta />.
This happened because the meta item was queued, and annotations didn't
trigger metadata queue flushes. The fix is to trigger a metadata queue
flush whenever we're about to write something that isn't itself queued.

Objectives:
* Associate models with tools, rather than dialogs and inspectors
* Move tool/model association utilities to ve.ui.ToolFactory
* Obliterate the view registry
Notes:
The only special case for leaving modelClasses definitions in place is
for the linkInspector. It uses these for selection expansion.
Because tools can now override the static canEditModel method, we can
dynamically evaluate a model, rather than be restricted to only
comparing classes. This will be useful for disabling editors for models
that are for some reason incomplete or otherwise broken and cannot be
safely edited.

HTML like <td><span>Foo<!--bar--></span></td> would lose the comment
when converting to linmod, and so we'd drop the comment when converting
back to HTML.
This happened because we were queueing up meta items to possibly move
them and their whitespace out of the wrapper paragraph even if we were
inside of an annotation and there was no way we could move things out
at all. The fix is simply to detect these case and not queue up meta
items in that case.

Fixes (follows-up I1b48ef5240, I6daff5c596):
* Invalid html passed to jQuery constructor.
* Use prop() instead of attr() for boolean values.
* Use append() instead of html() when appending nodes instead
of parsing html.
* Rename shadowed variable name clash 'mw' to 'mwData'.
* Fix odd construction where we parse '{}' to create an empty
object.
* Have ve.ce.MWReferenceListNode#update perform changes off-document
in a detached tree.
* Fix deep property access that can fail. mwData is set to
either JSON parse of data-mw attr or empty object.
Accessing mwData.attrs.group needs to be guarded by whether
mw.attrs is indeed set.
* Have `mw` and `about` attribtue in references list roundtrip
(especially mw which can data we aren't editing/re-creating).
* Add missing 'refGroup' property to MWReferenceListNode's
data element (similar to what MWReferenceNode already has).

At the moment we create an alien meta item if an annotation
wraps contents of zero length, however we also need to handle
nested empty annotations, i.e. where the contents is other
empty annotations (i.e. alien meta items).
As alien meta items simply preserve DOM elements we don't
mind what type of alien meta items they are, so this also fixes
the case of an annotation wrapping another alien meta
e.g. a comment or <meta> tag.

This function builds a transaction that takes a document slice and
inserts it back into the document it came from, applying any changes
that were made.
This makes editing document slices simple:
slicedDoc = doc.getDocumentSlice( captionNode );
// Edit slicedDoc using a surface
tx = ve.dm.Transaction.newFromDocumentInsertion( doc, captionNode, slicedDoc );
surface.change( tx );
Specifically, newFromDocumentInsertion replaces the node's contents
with the document's contents (meaning any changes made to the node in
the meantime are lost). It also merges the stores internal lists
of the two documents and remaps indexes accordingly. This means editing
of references inside of references is supported.
This functionality is not specific to slices, and can also be used to
safely insert data from a paste buffer, with internal list data being
transplanted correctly.
ve.dm.MetaLinearData:
* Make merge( [ undefined, undefined, ... ] ) return undefined rather
than [].
ve.dm.Document:
* In getDocumentSlice, store a pointer to the original dm.Document in
the new one, and also store the length of the internal list. This
allows us to figure out which internal list items the two documents
have in common when we insert the modified slice back into the main
document.
* In getMetadataReplace, optionally take the inserted metadata as a
parameter, to allow for operations that insert both data and metadata.
Per Ed's review, rewrite this function to return null rather than {}
if no metadata needs to be replaced.
ve.dm.InternalList:
* Add method to merge two internal lists
ve.dm.Transaction:
* Remove newFromNodeReplacement and replace it with newFromDocumentInsertion.
* In pushReplace, optionally take the inserted metadata as a parameter.

Previously we populated the reference body into all <ref> tags
with the same key. Now we store an internal attribute marking
which element originally had the data.
If that tag is deleted the body is moved to the first <ref> tag
with that name.
