erwin.coumans 3ca977e39f Patch by Nathanael Presson: (needs some more work, some of the demos don't show properly (RayCaster, CollisionInterfaceDemo,'g' key is already occupied in ConcaveDemo etc)
btDbvtBroadphase:
- Fixed a performance issues reported by 'reltham'
- Added btDbvtBroadphase::optimize() for people who want good performances right away or don't do dynamics.
- fixed compilation issues when DBVT_BP_PROFILE was set.

btSoftBody:
- Fixed singular matrix issues related to polar decomposition (flat meshes).

DemoApplication:
- Shadows (enable/disable through 'g' or DemoApplication::setShadows(bool)).
- Texture can be enable/disable through 'u'

CDFramework:
- fixed compilation issues.
