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.

27aa959059 fix some btMultiBody URDF conversion issues in ImportURDFSetup 
remove various vertex format structures and use GLInstanceVertex from #include "OpenGLWindow/GLInstanceGraphicsShape.h"
btMultiBody::setupPrismatic takes an additional argument to allow a shift of inertia tensor, relative to the joint frame (link frame at q=0)

488dd44835 Added btMultiBodyPoint2Point, it can be used between btMultiBody vs btMultiBody or btMultiBody vs btRigidBody 
Allow picking of btMultiBody, using a btMultiBodyPoint2Point constraint, with limited strength to avoid adding too much energy to the system (= blowup)
Add btMultiBodyJointMotor, it can be used in combination with joint limit (just add the joint limit after the motor, to avoid jitter)

2fb686b937 change btMultiBody to allow removal/changing of links 
(still not easy to modify the link structure of a btMultiBody -> You have to manually re-link parents, copying links around etc)
