Undo Function

A simple keyboard shortcut like CTRL Y to undo the last action.
Can't count the times I accidentally deleted a building when working on belts and pipes ...

This would be especially useful when working with Blueprints and accidentally deleting or adding something that just messes everything up and is a time-consuming pain in the butt to undo manually. Maybe somewhat less realistic when it's something that already exists, as opposed to a Blueprint, but perhaps it could be made to work.

I knew I'm not the only one with such a problem. Cutting whole planned project to move it to destination, one wrong button press and one (or more) hour gone...

I did it few times, cut a designed factory to move it a little bit, found out there's something in the way, hit escape. Poof, the entire thing is gone instead of snapping back to it's original place.

Ctrl-Z to undo, Ctrl-Y to redo. Keep a history of the last 10 or so actions.
