* Moved implementation of getting and updating a DOM wrapper to ve.ce.BranchNode
* Updated ve.ce.BranchNode tests
* Renamed ve.NodeFactory.createNode to ve.NodeFactory.create
* Added ve.NodeFactory.lookup which gets the constructor of a type
* Added attribute pass-through to ve.dm.BranchNodeStub
Change-Id: I8f5b7d3d3ae616cc5f39828b24b655163d782ae5
* Also fixed calls to addListenerMethod
* Also routed adding children in the constructor of ve.dm.BranchNode to the splice method
* Renamed types of ve.dm stub nodes to avoid collisions (since we have to register ce nodes by the same names for them to be generated by onSplice)

* Also renamed convertDomElement to replaceDomWrapper in ve.ce.BranchNode
