Bullet 2.43 release: compressed AABB tree, 16 bytes per node

[Erwin Coumans]

Bullet 2.43 is released.

Main improvements:

- compressed AABB tree: 16 bytes per node, quantized aabb, with 32-bits indices. This helps reduce memory usage of large triangle meshes, with improved performance. See Demos/ConcaveDemo
- COLLADA import improvements. See Demos/ColladaDemo.
- Improved performance for convex polyhedral shapes. The local AABB is cached, instead of re-computed each frame. This caused a major slowdown for larger scenes, in particular .bsp levels with many convex hulls.
