Many of the aircraft that we use for DEAD are not actually capable of
the SEAD task in DCS, so they were being loaded as some other task type,
usually one that doesn't support Attack Group, which made them lose
their waypoint actions and do nothing.
This switches them to using CAS which supports a superset of the SEAD
capable aircraft.
I've also audited the SEAD/DEAD lists. The F-117 was removed because it
is not capable of Attack Group *at all*, and all the non-SEAD aircraft
that are capable of ground attack moved from SEAD to DEAD.

Still a work in progress (the missions don't actually perform their task, just orbit). Currently:
* AEW&C aircraft can be bought.
* AEW&C missions can be planned at any control point and at front lines.
* AEW&C will return after 4H or Bingo.
Also separate out SEAD and DEAD taskings. Some aircraft can DEAD but not SEAD.
Also make the recruitment menu use the pretty names in the alphabetical sort func.
Rather than randomly selecting compatible aircraft for missions, perfer
the *best* aircraft for the job. This removes the "preferred" lists in
favor of sorting the capable lists in priority order. To maintain some
amount of variety the procurer has a 50/50 chance of buying when it
finds a match.

AI aircraft purchase decisions are now driven by the missions that the
flight planner was unable to fulfill. This way we're buying the aircraft
we actually need instead of buying them at random, in the locations we
need them, in the order they're needed.
There's a bit more that could be improved here:
* Unused aircraft could be ferried to where they would be more useful.
* Partial squadrons could be completed rather than buying a whole flight
at a time.
* Aircraft could be ranked by their usefulness so we're not buying so
many Hueys when a Hornet would do better.
* Purchase a buffer of CAP capable aircraft in case too many are shot
down and they are not available next turn.
