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. https://github.com/Khopa/dcs_liberation/issues/361
