Title: ENH: TreeEditor: Added on_activated trait to TreeNode.

This complements the activated trait of TreeEditor, and allows
TreeNodes and related classes (TreeNodeObject etc.) to implement
functionality when a TreeEditor's node is activated
(double clicked or Enter key is pressed when the node has focus).
Also fixed a bug in vetoing to double click events on wx backend.
