Keyboard configuration fixed

Apparently the last update made the keyboard configuration bugged despite me not touching the code for it. I guess that is programming for you :P It should be in working order again now. I would like to eliminate as many bugs as possible from the game, so if you encounter more feel free to tell me about them. Some of them are tricky for me to recreate though, GameMaker games tend to behave differently on different machines making certain bugs very hard to fix. This is totally not an excuse, more of an explanation :P I definitely want the game to be as bug-free as possible like I've mentioned before. -Servadac
