Fix undo for resizing linksets

This involves implementing a boolean in UndoState to signal whether the undo needs to be done for an entire group/linkset or just a single prim
Resizing individual components of linksets is still dodgy.
Resizing still has to be down twice, since for some reason the client is sending two multiobjectupdate packets on every resize except the very first.  This applies to single prims and linksets.  Need to look into this.
