toggle backface culling

just to practice my mel scripting abilities a bit i extended my backface culling switching process to be a toggle so it can be turned on and off just with one hotkey. before i switched between backface culling on and off with ctrl+1 and ctr+2, now i just use ctrl+1 and press it again to toggle. once again, some milliseconds saved per action. download the script here and put it’s content into a hotkey handler (thanks to sven steinbauer for his xray toggle object script which this script is based on).
