we_undo

Undoing reverts changes of nodes (name, param1 and param2) and metadata. Node timers are not yet supported. The undo functionality should help against accidents; however, it should not be considered reliable since there is no guarantee that undoing always is possible or works correctly.

The changes of nodes after invoking a command such as /set are compressed to improve memory usage.

TODO

Add parameters to undo and redo: undo the last n
Allow undoing changes which happened before other changes (considered unsafe) e.g. //undo ~1 to undo the change before the latest one
Add times to the changes, show in //show_journal
Implement more commands
worldedit pyramid fix
Fix the shown "nodes changed" count
