[Request] Simple change- Size counter

[Emptyz]

Just requesting a addition to the game where it shows how big the current selection you have is. eg: i select 5 blocks up 10 wide, it would say 5x10 or which ever format you would prefer, just would make the game feel a little more polished and save me some time counting each block to make sure im making the room the right size.

Shouldn't be that hard to mod in, if i understood the game a little more i would attempt it myself.
