90f96aec27 Introduced btActionInterface. This makes it easier to extend user-defined actions, such as vehicles and characters. 
btRaycastVehicle and btKinematicCharacterController are derived from btActionInterface now.
Some cosmetic cleanup: changed sourceforce/sf.net url to bulletphysics.com.

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

65bb612598 - added quickSort to btAlignedObjectArray (has generally better performance then heapSort) 
- replaced all usage of heapSort by quickSort
- finished btMultiSapBroadphase. Still some work to be done to increase performance (faster add/remove from child broadphases. 
  uses currently AABB tree to locate child broadphase (should use grid), and sorted array takes too much time.
