Simple Trailer logic

I would like to propose a alternate projectile trailer system as another option due to the concept of original westwood implementation must spawn always new instance of animation in order to follow projectile... depending on anim instance frame lenght this bogs easily down as instances amount rises and that particular logic does not have any frameskip function either to accelerate itself to avoid fps drop.

My suggestion is to bring new feature that instead follows projectiles by looping single anim instance (instead of spawning endless new instances within TrailerSeperation/SpawnDelay frame delays, not so different to AE anim except would follow behind.

This would cut down on lag in the trailer applications where simpler trailer logic would be fitting, such as rocket exhaust flame.
