[Soc-2013-dev] Weekly Report #4 Rigid Body Simulation Improvements

[Sergej Reich]

This week I:
* Added custom center of mass for primitive shapes.
* Added compound shape support, some issues sill remain here, especially
  modifying collision shapes while the simulation is running.
The problem with both of these features is that they make the simulation
unstable when using certain collision shapes (compound shape bug in
bullet it seems). I've spent quite some time debugging this, but didn't
find a good solution yet :/
* Started playing with the HACD library to do convex decomposition.
* Investigated rigidbody/bullet related bug reports.

Next week I'll continue working on convex decomposition and looking into
bugs.
