Title: Oskuundo

This adds the undo functionality for leftover commands, by implementing class DiffAnything which diffs lines and saves the difference.

Infact DiffAnything can drop-in replace FullCopy, and has the potential to save a lot of space if the range of the changes are minimal.

Another commit adds the toolbar icons.
