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 initial examples, replacing the 'Demos/Demos3'. Will make it work cross-platform, OpenGL3/OpenGL2 and add more examples to it.
