Interaction Features (#101)

Various minor interaction features.

There is no concept of gravity in the game yet, so items drift through space or the hallways of a station until they are stopped. Thrown items do not collide with walls because making them collidable makes them collide with EVERYTHING, including the player. We need collision groups in the physics system.

Because of the previous problems the velocity things are throw at is set quite low, it can be tweaked after the other mentioned issues are resolved.
