Add rotation support

[yckart]

Would nice to see support for rotated objects (using SAT, swept OOB...) for collision tests, and the colliding angle in collision response.

I agree!
I'm not able to add these right now because of time constraints, but if anyone out there reading this is able to help, we would greatly welcome it :)
