fix many warnings remove btMultiSapBroadphase.* make collisionFilterGroup/collisionFilterMark int (instead of short int)
enable URDF loading throught the 'File/Open' menu set a default camera targets for each demo. note that it is only reset when switching to a different demo, so you can restart at your chosen location. no OpenCL pairbench drawing in OpenGL2 (there is no VBO available etc)
add OpenCL PairBench (missing GUI, so not really useful)
