Allow the user to set the Undo Key for Condos in the Controls menu

I keep accidentally undoing the last edit I make in Condos because I press Z to zoom in on something forgetting that it’s not an undo key, it would be nice to have the option to change the Undo key in the settings menu so that it does not overlap with zoom - because as far as I can tell that option does not exist, or better yet just change it to the U key or something as the default even.
