This license change is aimed at maximizing the reusability of this code
in other projects. VisualEditor is more than just an awesome editor for
MediaWiki, it's the new editor for the entire internet.
Added license and author files, plus mentions of the license to all
VisualEditor PHP, JavaScript and CSS files. Parser files have not been
modified but are effectively re-licensed since there's no overriding
license information. 3rd party libraries are not changed, but are all
already MIT licensed.

Ground-up rewrite of the data model. Putting this in the ve2 directory for now so we still have the old code floating around.
Main changes so far in this rewrite:
* Renamed hasChildren() to canHaveChildren()
* Added canHaveGrandchildren()
* Added a new node type TwigNode that can have children but not grandchildren (so all of its children must be LeafNodes)
* Implemented push/pop/shift/unshift as wrappers around splice()
* Renamed getElementType() to getType(). Nodes now take a string as a type, and the element stuff is gone and won't be back
* Removed clearRoot(), replaced it with setRoot( this ) where needed

This has some TODOs still but I want to land it now anyway, and fix the
TODOs later.
* Add this.offsetMap which maps each linear model offset to a model tree node
* Refactor createNodesFromData()
** Rename it to buildSubtreeFromData()
** Have it build an offset map as well as a node subtree
** Have it set the root on the fake root node so that when the subtree
is attached to the main tree later, we don't get a rippling root
update all the way down
** Normalize the way the loop processes content, that way adding offsets
for content is easier
* Add rebuildNodes() which uses buildSubtreeFromData() to rebuild stuff
* Use rebuildNodes() in DocumentSynchronizer
* Use pushRebuild() in TransactionProcessor
* Optimize setRoot() for the case where the root is already set correctly
