asciiArtToMap() and Overwrite Mode, FTW!

I used Akihabara's asciiArtToMap() for both my Ludum Dare 20 and my Experimental Gameplay Project video games. TextMate has a feature called Overwrite Mode that makes editing the maps super easy.

I also extended the functionality of asciiArtToMap for Commander Clone so that I could place the % character into the map in order to visually place objects. No more calculating x,y coordinates manually!
