Message:

orxonox/branches/chris: Implemented basic track and spawning functionality. Added a function to convert a Rotation into a glmatrix. Implemented operator* in Rotation. Refined World, made World friend class of world_entity. Implemented camera functionality (can now be bound to the worldentity it should focus on).
