Added a Damage class to pass damage value and damage(types) instead.
This removes a great amount of overhead and longterm opens possibilities to have damagetypes without warheads.
At least in theory, it's possible for an actor to have multiple AttackFollow traits, or AttackFollow is disabled initially but enabled via upgrade later.
To avoid crashes or other issues, let's play it safe and take the same approach as with AttackBase look-ups.
Most auto target scans will be conducted among groups of allied units unable to target each other because they are allied and their weapons only target enemies. Since they cannot target each other, the scan will be repeated constantly. Realising this, we can significantly reduce the performance impact of auto target scanning by bailing early in this scenario to avoid carrying out expensive targeting checks on friendly units which we know will fail anyway.
Avoid using LINQ for filtering, grouping and dictionary building. Instead, we do these ourselves to reduce overhead.
Actors are checked for AutoTargetIgnoreInfo (rather than the trait) since info checks are marginally faster. This check can now be done immediately to allow us to skip such actors right away.
The ClosestTo calculation is now only run on the group on actors for the selected armament, rather than all potential armaments.
Enabled firing multiple armaments at a target simultaneously.
Each armament defines own cursor for targeting.
The force attack modifier influences armament choice for target.
Autotargeting modified to handle firing multiple armaments simultaneously.
As a consequence, healers (medics) no longer require separate Heal
activity and AttackMedic and AutoHeal traits.
