add initial pybullet module, using the shared memory API

(for now, start the example browser in 'physics server',
then compile using premake --python option,
then run python in the bin folder (so it finds pybullet.so)
and run the test.py script in examples/pybullet folder.
The robotics shared memory C API is very suitable for this.
