1) Began the process of converting the user from a simple cameraman to a ship:

The forward/back keys now control a thrust component instead of arbitrarily changing the position of the camera. Thrust is applied in the direction of the camera view.

2) Removed the pseudogravity which caused shards from exploding ships to "fall" to the "ground". The game will be based in zero-g, so all particles should react accordingly. Therefore there exists no real "floor" or "ceiling" to the cube arena, but the walls may be distinctly textured to help with orientation while playing.
