Select / Copy / Mirror / Paste Terrain

Please add functionality to select, copy, mirror (through any axis/degrees) and paste terrain. Having even a basic manner in which to select, copy and paste would be a start, but so much more can be done than just what we can already do in MS Paint.

Being able to do this within the same map will allow for multi-level structure support with very little extra coding requirements and would make map building far simpler, therefore more enjoyable and more consistent as a finished product, which will allow us to sing Dungeon Alchemist's praises far easier!!!
