5d40d90bd0 add btMultiBodyConstraint::finalizeMultiDof API: if you add multi-body constraints to a multi-dof btMultiBody, before it has been finalized using the btMultiBody::finalizeMultiDof call, 
then you have to manually call the btMultiBodyConstraint::finalizeMultiDof for all multi-dof multi body constraints.

92dabdc07d Fix a couple of bugs in 2dConvex Hull algorithm. 
* Need to use atan2 so 3d angles are calculated properly after projection.
* Need to handle case where the first tripple of points is non-convex,
previously this would cause the algorithm to fail with only 1 point.
