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.
The changes for Skynet unfortunately broke this because the names used
by the TGO and the name of the group itself were no longer in sync.
This deserves a larger cleanup where we decouple that naming
requirement (TGOs don't need a lot of the data they currently have),
but this works until we have the time to do that.

Mission generated now configure bluefor and redfor coalition properly, so it is possible to use country that are not in the default coalitions.
Added insurgent faction.
