Floating Monkey Heads

With sincere apologies to Suzanne, basic entity logic is working. You can pilot your own floating monkey head around, colliding with walls and other entities. The only actions supported are 'wait', 'move' and 'turn', each with its own time cost. Now that the obvious bugs are worked out of the action timing, it will be nice and easy to extend these.

I switched to a free camera for debugging, and enabled geometry for the player. You control the green disembodied primate noggin in the screenshot:

Nothing interesting to report, except that the effect of a bunch of floating monkey heads drifting around is... distinctly creepy. I am very unnerved.

Oh, yes, ugly textures too. Did I mention those?
