* Fixed constructor of ve.ce.BranchNode which was calling the wrong method to perform an onSplice and with the wrong arguments
* Removed/renamed events emitted from ve.ce.BranchNode.onSplice
* Reintroduced .$ to all ce nodes
* Ported over functionality for DOM node type variance used in headings, lists and list items
* Moved the old ve.ce.Content guts to ve.ce.TextNode
* Added getOffsetFromNode and getDataFromNode to ve.dm.DocumentFragment
* Added setDocument and getDocument to dm nodes
Change-Id: I185423ba2f1a858dde562cb2f5bc3852aec930db
* 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

Image nodes are leafs, so providing an empty array to their children/length "contents" constructor argument ends up setting the numeric length to [], which casts to an empty string in arithmetic, causing all further calculations to be concatenations instead of additions.

* Indexes for attribute references were off (the comments that were previously wrong before were relied on and cause this to also be wrong)
* Tree should start with a document node

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