efaef89c5f Add a shortcut function for quaterion/vector multiplication.
I got the idea from blender when I discovered by accident that quat * vect
produces the same result as quat * qvect * quat* and looked up the code to
check what was going on. While matrix/vector multiplication still beats the
pants off quaternion/vector multiplication, QuatMultVec is a slight
optimization over quat * qvect * quat* (17+,24* vs 24+,32*, plus no need to
to generate quat*).

12e238f806 Add a function to convert quake angles to a quaternion.
The test works by comparing the result of AngleVectors with forward,
right, and up vectors rotated by the quaternion resulting from AngleQuat.
