* Also removed beforeSplice and afterSplice in favor of just plain splice which is the same as afterSplice used to be - beforeSplice was never used and it was making things more complex looking than needed

* Added support for asking if a given node type can have children or grandchildren and what types of nodes can be it's parent or child
* Removed canHaveChildren methods from leaf and branch nodes and converted use of them to depend on factory to read static rules from constructor lookup by type

And fixed ve.dm.DocumentFragment constructor to generate a correct offset map which creates references to branch nodes only

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
