To improve IADS design in campaigns, this differentiates required long
and medium range SAMs. SAMs that must be long range SAMs are defined by
SA-10 or Patriot launchers, while medium range SAMs are defined by SA-2,
SA-3, or Hawk launchers.
Long range SAMs positions will only be populated by long range SAMs
(Patriots and SA-10s), and not all factions have those available. Medium
range SAMs currently comprise all air defenses that are not long range
SAMs, so if the faction includes flak guns in their `sams` property then
flak guns may be spawned at medium range SAM locations.
Base defenses and random SAM locations continue to use either type of
SAM.
Doesn't allow helos or harriers to do it either even though they should
be able to because we don't currently support ground spawns, which would
be needed to prevent those aircraft from using the runway. Even then, I
don't know if they can be forced to *land* vertically.
Fixes https://github.com/Khopa/dcs_liberation/issues/432
Repairing a damaged runway costs $100M and takes 4 turns (one day). The
AI will always repair runways if they can afford it. if a runway is
damaged again during the repair the process must begin again.
Runways are still operational despite what the UI says. Preventing the
player and AI from using damaged runways (except for with helicopters
and harriers) is next.
Apparently we were already getting this info because it's a unit like
any other according to the event system, so if runways were actually
sufficiently damaged we'd emit a ton of exceptions.
This doesn't do anything yet, but tracks the damage state. Will add the
ability to repair them next, and then finally make the damage render the
runway inoperable.
Locations that should always be SAMs should be done with fixed IADs
locations, so we don't need the separate type.
The generic "ground strike location" needs to be eventually split up
into more specific types, so eventually all of the non-base defense SAMs
will go away.
