Math Lib:

* inline some more functions, from math_base and math_vector
* also made some changes to the way inline is done so it can
  work for more than one file
* reflect_v3_v3v3 requires input vectors to be normalized now.
* added rgb_to_grayscale
* added zero_v4, copy_v4_v4, swap_v4_v4, is_one_v3
* added box_clip_bounds_m4 to clip a bounding box against a
  projection matrix
