Campbell Barton 0a0f4c9d81 Mathutils refactor & include in sphinx generated docs, (TODO, include getset'ers in docs)
- Mathutils.MidpointVecs --> vector.lerp(other, fac)
 - Mathutils.AngleBetweenVecs --> vector.angle(other)
 - Mathutils.ProjectVecs --> vector.project(other)
 - Mathutils.DifferenceQuats --> quat.difference(other)
 - Mathutils.Slerp --> quat.slerp(other, fac)
 - Mathutils.Rand: removed, use pythons random module
 - Mathutils.RotationMatrix(angle, size, axis_flag, axis) --> Mathutils.RotationMatrix(angle, size, axis); merge axis & axis_flag args
 - Matrix.scalePart --> Matrix.scale_part
 - Matrix.translationPart --> Matrix.translation_part
 - Matrix.rotationPart --> Matrix.rotation_part
 - toMatrix --> to_matrix
 - toEuler --> to_euler
 - toQuat --> to_quat
 - Vector.toTrackQuat --> Vector.to_track_quat
