* 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.
CaptureDelay is defined per-trait, and the shortest
delay will be used if multiple traits are enabled.
CapturingCondition and BeingCapturedCondition are
global, and are granted when any capture is in progress.
The capture period is defined from when the unit reaches
the cell next to the target, and either starts to wait
or enter the target through to when the capture succeeds
or fails.
This fixes the various edge cases that occur when multiple
Captures or Capturable traits are defined on an actor and
are toggled using conditions.
The Sabotage threshold field moves from Capturable to
Captures in order to simplify the plumbing. The previous
behaviour ingame can be restored by creating a new
capturable type for each threshold level, each with their
own Captures trait.
Should save a trait look-up for each path search. Also ditch bogus null checks (this trait is a must-have anyway, so we *want* to crash if it's missing).
During heated battles, those TraitsImplementing look-ups in Health might cause bursty CPU load on warhead impacts. Caching the notify traits of the actor + owner can reduce the trait look-ups per impact by more than half.
