[Combo] SummonSelf

Airbending [Combo] SummonSelf 1.1

-Fixed the possibility of spawning multiple instances of the ability. The ability will now remove itself after 2 seconds of no activity.
-Added collision detection with abilities AirShield and FireShield. If it hits either of these abilities it'll remove itself.
-Fixed the knockback application to both user and target. It'll now apply knockback no matter where you are looking (as opposed to no knockback if you looked direction up or down).
-The knockback done to the target is now applied based on the direction of the blast rather than the initial direction of the user.
-Lessened the amount of particles by nearly half.
