Still more non-magecrawl work...

I keep promising myself that I'll get back to magecrawl soon, but right now this libtcod/SWIG work is keeping me busy. I've almost gotten the Console, Colors, and System classes wrapped. I find that googling for what I want to do is almost strictly better than looking it up in the documentation.

I'm figuring that once I get the hang of all the operation types I need to do in the conversion, that adding additional modules to the SWIG build will be easy. We'll see how well that assumption holds...
