40dc18f604 remove Extras/obsolete/quickstep 
improve serialization based on feedback: make it easier to serialize a single object, or single shape, or single bvh.
Modified Bullet/Demos/ConcaveDemo to use btSerializer to serialize the btOptimizedBvh (or optionally the trimesh+bvh)

You can also serialize trimesh without BVH, use:
serializer->setSerializationFlags(BT_SERIALIZE_NO_BVH);//	or BT_SERIALIZE_NO_TRIANGLEINFOMAP

d4c3633405 Get rid of btSolverBody and use btRigidBody directly. btSolverBody didn't improve performance after all, due to random-access 
Tweak the BenchmarkDemo a bit: 

1) disable deactivation in graphical mode
2) add some settings that increase performance in the BenchmarkDemo2 (1000 stack) from 35ms to 15ms on this quad core (at the cost of a bit of quality)

f552a1dbbf Remove first argument from btMultiSphereShape, calculate local inertia approximation from aabb. 
If user wants more accurate inertia tensor for multi-sphere shape, use btCompoundShape instead 
(amd btCompoundShape::calculatePrincipalAxisTransform)

6c80353556 Minor fix in friction: calculate second friction direction based on un-scaling first friction direction (issue if it was scaled to zero) 
Force activation state of static objects to be ISLAND_SLEEPING, once they are added to the world
Add backwards compatibility option btDiscreteDynamicsWorld::setSynchronizeAllMotionStates, just in case only updating active objects broke someones code

700db838b1 Add 1D and 2D support for Bullet: using rigidbody->angularFactor(const btVector3& factor) and body->setLinearFactor(const btVector3& linearFactor); 
For example, to only allow linear motion in the X-Z plane, and only rotation around Y axis use:
	body->setLinearFactor(btVector3(1,0,1));
	body->setAngularFactor(btVector3(0,1,0));
Fix build issues with CodeBlocks, when generating projectfiles using CMake 2.6:
