Collision Shapes

[rgrieder]

The physics engine implementation is working now, but has limited support for collision shapes: Only boxes, spheres and cones are supported, while cones are still not tested yet (cone.mesh can be used as graphical test).

On ​http://www.continuousphysics.com/Bullet/BulletFull/classbtCollisionShape.html, you can see a graphical overview of what collision shapes bullet offers.

For more information how to create a new collision shape, simply look at the ones in src/orxonox/objects/collisionshapes. It's not much and quite simple code.
