Added support for F-16D Barak Block 30 and Block 40 variants. Still using F-16C Barak banners as placeholders until I snap some good ones from the two-seaters.
Resolves#78
Would cause an exception because `PackageWaypoints.create(p, c)` would call `package.departure_closest_to_target()` on its turn which raises a runtime exception if no flights are present. Makes total sense when you think about it...
Fixes#66
Restored the default patrol duration handling in PackageRefuelingFlightPlan. Desired tanker on-station time will now only apply to TheaterRefuelingFlightPlan.
Resolves#67
The problem turned out to be split-triggers with no actions, which occurs when a STRIKE flight has no escorts in its package. Added a guard for this so the trigger isn't pushed to the mission in such a case.
This makes sure that aircraft spawning in the air due to a shortage of parking spots, will have the earliest TOT possible. Flights with later TOTs should be generated first so that they remain at the airfield as OCA target.
Resolves#57
"_generate_over_departure" is the method used to generate flights in the air when no more parking spots are available. Pydcs changes were required as it turned out aircraft were trying to spawn on helicopter parking spots, which forces them to start in the air by DCS itself.
Avoids choosing random squadrons during air wing configuration so that livery overrides takes precedence by default for a given aircraft type, unless the campaign file specifies a specific squadron. Users can still add a squadron manually which will automatically set the correct livery if they use a squadron preset.
Resolves#52
Should prevent mid-air collisions in most cases, though I'm still worried about "off map" spawns that can possibly collide, though an easy fix would be to manually use time-spacing.
Alternatively we need to treat it as a special case, assigning different altitudes to avoid collisions during the first leg of the flight if that turns out to be the case...
