#5 Undo - initial beta

[Michael Armida]

Included is a patch that adds Undo functionality. As SF doesn't allow you to attach multiple files here, I have put up the necessary files at the following location:

The following actions are currently undo-able:
- file copies
- file moves
- renaming
- creating links (relative and absolute)
- moving files to the trash

Additionally, this patch adds the command-z shortcut to the desktop and container windows. Furthermore, the "Undo" item now appears in usual Tracker windows.

I still have my doubts about the stability of this code in regards to memory leaks - I am doing my best to determine if its 100%.
