Trevor Parscal fd28fff50f Added test for replaceDomWrapper and onSplice in ve.ce.BranchNode
* 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)
