Refs #7140 Fixes the simple case where a tree node is dragged into one of it's child nodes.  This does not solve the more complex issue of a tree node with multiple parents being dragged into a child which cannot be readily determined by the tree.  Such cases will have to be solved by the user, with whatever data store they happen to be using.
