Depencency tree looked like this
* ext.visualEditor.viewPageTarget
- ve.init.platform
- ve.init.target
** ext.visualEditor.core
- (most ve.* classes)
*** ext.visualEditor.base
- ve.js
Some of the ve classes are calling ve.msg from the global scope
at load time (e.g. in the definition of static properties or in
constructors of classes that were immediately instantiated in
the same file).
Platform needs to be initialised in the base module.
ve.init.Platform.js was already there, but that's just an
abstract base class. The the ve.init.platform property is set
from the implementation classes' files.
Updated makeStaticLoader.php and re-ran for test and demo html.
The fake "Standalone Init" module is now gone, which shows that
this was needed as test/ and demo/ already put their platform
code in/after the 'ext.visualEditor.base' module in the html.

Created an IndexValueStore class which can store any object and return
an integer index to its hash map.
Linear data is now stored in ve.dm.LinearData instances. Two subclasses
for element and meta data contain methods specific to those data types
(ElementLinearData and MetaLinearData).
The static methods in ve.dm.Document that inspected data at a given
offset are now instance methods of ve.dm.ElementLinearData.
AnnotationSets (which are no longer OrderedHashSets) have been moved
to /dm and also have to be instantiated with a pointer the store.

* Make dialog a fixed width and have a minimum and maximum height while always being centered in the window.
* Add style for the outline panel
* Add border below the title
* Move font-size adjustment to child elements to preserve layout scale

* Added classes for styling purposes
ve.ui.FormatDropDownTool.js
* Modified call to menu item constructor as per changes therein
* Reorganized options config to make construction simpler
* Changed to setLabel after selecting the item to prevent the label from being changed to the wrong value as a side-effect of setting the item
ve.ui.DropDownTool.js

A MetaList is a collection of MetaItems representing all of the
metadata in a ve.dm.Document, and it updates itself live as the
underlying document changes.
Currently this interface is read-only, I'll add mutators next.
Change-Id: If7bfc9563af37e22dcdca9a682d6decc2f6f1872
Rather than meta-things being special kinds of nodes, they are now a
separate class of things (MetaItems) along with Nodes and Annotations.
* Created a generic ve.dm.MetaItem that meta items inherit from.
There will be actual instances of this class as well in the upcoming
meta group code.
* Renamed MetaNode to AlienMetaItem, MWMetaNode to MWMetaItem,
'metaBlock'/'metaInline' to 'alienMeta'

either a node or a meta item
* Handle meta items in getDataFromDom()
* In getDomFromData(), check the MetaItemFactory as well as the NodeFactory

This is a major refactor of user interface context, frame, dialog
and inspector classes, including adding several new classes which
generalize managing inspectors/dialogs (which are now subclasses
of window).
New classes:
* ve.ui.Window.js - base class for inspector and dialog classes
* ve.ui.WindowSet.js - manages mutually exclusive windows, used
by surface and context for dialogs and inspectors respectively
* ve.ui.DialogFactory - generates dialogs
* ve.ui.IconButtonWidget - used in inspector for buttons in the head
Refactored classes:
* ve.ui.Context - moved inspector management to window set
* ve.ui.Frame - made iframes initialize asynchronously
* ve.ui.Dialog and ve.ui.Inspector - moved initialization to async
initialize method
Other interesting bits:
ve.ui.*Icons*.css, *.svg, *.png, *.ai
* Merged icon stylesheets so all icons are available inside windows
* Renamed inspector icon to window
ve.ui.*.css
* Reorganized styles so that different windows can include only
what they need
* Moved things to where they belonged (some things were in strange places)
ve.init.Target.js, ve.init.mw.ViewPageTarget.js, ve.init.sa.Target.js
* Removed dialog management - dialogs are managed by the surface now
ve.ui.*Dialog.js
* Renamed title message static property
* Added registration
ve.ui.*Inspector.js
* Switch to accept surface object rather than context, which conforms
to the more general window class without losing any functionality
(in fact, most of the time the surface was what we actually wanted)
ve.ui.MenuWidget.js, ve.ui.MWLinkTargetInputWidget.js
* Using surface overly rather than passing an overlay around
through constructors

Heading and Preformatted nodes have rules that should only
exist under a document node in MediaWiki.
Two new node types have been created as has a new DropdownTool which
uses these. The MW init options have been changed to use the new
DropdownTool.

Add a static.name property to ce nodes and make sure both ce
and dm nodes always use the static.name property in constructors
and registration calls.
The result of this is that any given node type should now only
appear once in the code as a string.

CE doesn't actually render meta nodes anymore now that we split them out
into the meta-linmod.
I took a stab at consolidating metaBlock and metaInline (into simply
'meta'), but we can't do that with the current node API unless we put a
lot of meta-specific hacks in the converter. So I'm leaving this for the
node API rewrite.

Although $.toJSON optimises heavily for modern browsers (it
becomes a direct reference to JSON.stringify), we still load the
extra plugin.
JSON is specified as part of ECMAScript 5, but most browsers
supported this one before they supported the rest of ES5.
http://caniuse.com/#search=JSON
Cut off for native JSON is IE7, Firefox 3.0 (3.6 supports it) and
Safari 3. Not any of our concern as VE will most likely never
support those (certainly not at this point in time, and less
likely as time goes on).

en.wikipedia.org has a template gala for edit notices with a whole
bunch of html framework outputted by default from
MediaWiki:Editnotice-0 (even if their underlying system has no
matches for the current page).
In the core editor from EditPage.php this isn't a problem as the
element is just idling hidden above the editor.
In the case of VisualEditor (where we have a custom delivery for
the edit notices) we don't want to say "1 notice available" on
every page, so we need to be smart and quickly walk the dom of the
notice, filter out invisible nodes, and if the resulting nodes
have no contents, ignore the notice all together.

Basically saveDialog-body now has three slides:
* review
* report
* save
There is a viewPage.swapSaveDialog method that is called like this
viewPage.swapSaveDialog( 'review' );
initially called from showSaveDialog.
Misc:
* Replaced more reused core message with a ve ones:
savearticle => visualeditor-savedialog-label-save
showdiff => (removed)
* Removed min-height from saveDialog. When slide-review is
load, it is very short and there shouldn't be 10em's of
whitespace below the loader + buttons.
To avoid problems with diff cache being cleared while looking
at the save dialog, we lock and unlock the surface.
We could later remove this as and optimise it as feature, but for
now this fixes a bug.

Rename methods consistently to enableFoo and disableFoo.
Use mw.notify instead of mw.util.jsMessage (the latter takes a
string of html and parses it, instead of taking text).
Also, jsMessage is obsolete (legacy wrapper around mw.notify).
Rename slide-main to slide-save in preparation of other slides
and introduction of multi-step save dialog.
Re-introduce "disabled" state (not css, but actual state) so that
pressing "Show changes" multiple times will not spawn multiple
async operations. The save function guards against this by keeping
a static property in the internal helper method, but there are
still some operations happening between the button and that method
this should be guarded in the UI instead. Follows-up I67819168.
