* 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
