[Open Beta] Procedural On-the-Fly Animation in UE4: iTween!

I removed it because it had been rolled into the engine’s SetActorRotation base function. It should already be taking the shortest path! But if the behaviour is not as you expect, I can look into reimplementing it for the next version. If you have some steps to reproduce an issue where the rotation is not what you expect, please do share them as this will make it easier for me to implement a version local to iTween.
