Added context menu items for collapsing and expanding nodes

Summary:
Added 3 context menu items:
- expand recursive
- collapse recursive

These are self explanatory.

I also collapse non ancestors. This collapses everything except your direct ancestor path to the root. Quite useful to refocus the tree on a node

Changelog: UIDebugger - added  context menu items for exanding and collapsing the tree.
