Reverted Josh's changes to the Universal_System/scalar.h, after reviewing
the changing again, I realized he actually is wrong. Box2D functions work
in radians, since Game Maker uses degrees, the functions have to take
degrees and convert them to radians, and functions that give you an angle
must take radians and return degrees. The entire purpose of the angular
macros is so you can switch to radians and eliminate all degree
conversions, if you are working in radians, like every API ever, then
there is no need for any conversion to or from degrees.
