Euler to quat reversion

Testing using the regenerating turret https://github.com/Azaezel/Torque3D/tree/outpost_testbed_clean shows that tracking is precisely inverted using #718 (https://github.com/GarageGames/Torque3D/commit/8b1ff267f09381e51f851af0373588a004e8a376#diff-983ceaf4b3cbddd4701734aaa048a79e). reversion PR till someone has time to properly review whether that's fouled conversion on my part, or if turrets were accounting for bad math to start with.
