Fixes Unreal Engine view angle matrix order

Browse Source 
The view angle rotation matrix order in Unreal Engine was incorrect, leading to incorrect camera orientation.

This commit fixes the order of rotation matrices to roll, pitch, yaw
to correctly implement Unreal Engine camera rotations.

Adds comprehensive unit tests for Unreal Engine formulas, camera and constants.

Marks Unreal Engine as supported in README.md.
