Allow Bullet soft bodies to be created using a AddObject actuator. Added a fake world coordinate system to game soft bodies, although the vertices are already in world space.
Added Bullet/Gimpact concave collision detection to Blender. If your build system isn't updated yet, please add extern/bullet2/src/BulletCollision/Gimpact/*
This allows moving/dynamic concave triangle meshes (decomposing meshes into compound convex shapes, and using 'compound' shapes is still preferred)
