Fix for issue #654 TranslateAnimation3D setOrientToPath() not working in new Animation Framework
In the original version of this class a delta value was used for the lookAt function. This was accidentally replaced by elapsed time.
I guess this was caused by confusion over delta time and lookat delta.
I've created a new variable called mLookatDelta to avoid future confusion.
