Changeset 2453 for code/branches/physics_merge/src/orxonox/objects/worldentities/pawns

Message:

SpaceShip is now harmonising with Bullet as well. The attributes of the steering can be configured in the XML file. I recommend a very high angularDamping or otherwise it will get very tricky to steer the ship (however more realistic).
