* Adds support for linking Armor traits to HitShapes.
* Adds spread support to TargetDamageWarhead
* Removes ring-damage support from HealthPercentageDamage
* Removes IsValidAgainst check from DoImpact(Actor victim...) overload
and instead lets warheads perform the check beforehand
(to avoid HitShape look-ups on invalid targets).
* Reduces duplication and improves readability of Warhead implementations
Added Takeoff & Landing sounds to planes.
Changed Aircraft Trait, TakeoffSounds & LandingSounds are now arrays & accept a list of sound files & it will randomly select one to play.
Changed/fixed take off & landing sounds to originate from the aircraft location, rather than play a global sound.
This is the safest approach to avoid conflicts/visual glitches when the host is responsible for both resupply types.
The new trait will simply play a looping animation as long as the actor is resupplying in any form.
