Getting near enough to the finish line to start making some more polished demos.

When I first started this project I supported Newton, Bullet and PhysX engines. Somewhere along the line, though, I dropped Bullet and PhysX support ... mainly because Newton is the most stable of the lot, is the one being most actively developed and has by far the best support.
Thanks Julio!
