Hello again!

I was a little over-eager in declaring version 1.0/1.1. I am returning
to this project again. On the immediate TODO list:

1. Refactor the main body of the code, and make the classes legible.
2. Add a 2D camera.
3. Overhaul the graphics and sound. Detailed animation is no longer a
priority.
4. Specifically reign in some helper functions and classes that are
shoddily coded.
