Trying to make the tweakfile code more general purpose.
I'd like to just throw stuff in there and reference it in code without
having to modify structs and stuff.
So far it's tedious, but mostly because I'll have to go back and rewrite
a bunch of code... sadge.
Skybox example and working in game.
Need to do something cool to take advantage of it like moving the
camera, but it's there and I know roughly how to make one!
