HL_CalculateBones - calculate bone positions - quaternion+vector in one function HL_CalculateBones - calculate bone positions - quaternion+vector in one function

note, while ender may be proud of this function, it lacks the fact that interpolating eular angles is not as acurate as interpolating quaternions.
it is faster though.
