Using Radians instead of Degrees

The math libs in Haxe use radians, and FlashPunk originally used degrees because of AS3's math libs. I don't see why users should have to convert from radians to degrees going from the math libs to Haxe, and vice versa.
To do this I just ran a code search for 'angle' in the master branch, but everything SEEMS to be fine.

I can understand not wanting this change to be implemented because it would break projects that already utilize angles, but I feel like it's a worthwhile change.
