Finally upgraded to latest Bullet subversion, about to release 2.71. Some recent changes in extern/bullet2 need to be re-applied, will check with Benoit. Ray tests in 0_FPS_Template.blend is broken, didn't figure out why yet.

HELP BUILD SYSTEM MAINTAINERS: Please help with updating all build systems: the newly added files need to be added. Note that the src/SoftBody has been added for future extension of real-time soft bodies.
