started working on some serious performance improvements. now the union find is optimized, the broadphase add/remove overlapping pair was too slow. added a stl::set to keep track of overlapping pairs. this speeds up the set find/remove. work in progress.the SimpleBroadphase is broken. will be fixed tomorrow.

Did some tests with 3000 rigidbodies, works much smoother now :)
