[Soc-2012-dev] Weekly progress report 11 - Bullet Integration

[Sergej Reich]

This week I spent most of the time polishing various parts of the system
so it's nicer to use.
I started redoing the calculation of convex hull shapes so it's more
efficient and allows us to embed the collision margin.
Also I now have a pretty good idea of how rigid body constraints should
work.

Next week I should have the foundation for constraints finished and at
least have point to point constraints working.
