[cp-patches]: Patch: JTree editing and key handling completed.

[Lillian Angel]

JTree editing is complete and key handling is also complete.
- F2 starts editing, Enter completes the editing.
- Triple clicking and click-pause-click also start editing.
- clicking anywhere while editing, cancels the editing.

The patch is really annoying to read. Alot of code was moved around and
many comments were reformatted. If you need further clarification on how
I implemented some of these functions, feel free to ask.
