Add BulletWorldImporter: it takes the in-memory data from BulletFileLoader and instantiates objects in a BulletDynamicsWorld.

Note that BulletFileLoader is has no dependencies on BulletDynamics/BulletCollision.
Also added a custom build step to copy asset (.bullet and .obj file) into the executable folder
Made a few 'char*' 'const char*' to avoid compiler warnings
