Got the new tree to sort of look nice
Added a ton of stuff (really should commit more frequently). Finished implementation of stuff. Added tests for order editor tree. Will add tests for nav tree.
Wrote tests for nav tree. Going to try to remove old GWT Tree stuff.
Functional! Still needs cleaning up.
Fixed bug that screwed order up when moving a node with children in the editor tree.
Cleaned up WikiSubpagesTreeUtils
