b409abac09 Deltas of linear and angular velocities applied to rigid bodies now are kept between simulation steps. 
Read-only access functions added to btRigidBody to get these values
Several OpenCL functions are implemented for MiniCL

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)

7782952d6b Add a minimum solver 'batch' size to avoid solving many small (independent) islands separately

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:

a8ec916af0 Added Height Field Fluid Demo to Bullet. All code stored in the Demos/HeightFieldFluidDemo directory for now. 
Please see HfFluidDemo.cpp for examples of how to use the height field fluid along with buoyant collision shapes.

The implementation is still lacking in my ways:
1) Need to complete more collision algorithms for buoyant collision shapes
2) Support compound buoyant shapes
3) The buoyancy model isn't that great
4) Fluid volume can be lost over time
