Don't propose missions the air wing can't plan.

We were doignt his for escorts, but now that we quit planning as soon as
we find an unplannable mission (to save money for higher priority
missions), if we hit an early unplannable mission like BARCAP no other
missions wil be planned.

Maybe fixes https://github.com/dcs-liberation/dcs_liberation/issues/1228

## Fixes
* **[Campaign AI]** Fix procurement for factions that lack some unit types.
* **[Campaign AI]** Improved pruning of unplannable missions which should improve turn cycle time and prevent the auto-planner from quitting early.
* **[Mission Generation]** Fixed problem with mission load when control point name contained an apostrophe.
* **[Mission Generation]** Fixed EWR group names so they contribute to Skynet again.
* **[Mission Generation]** Fixed duplicate name error when generating convoys and cargo ships when creating manual transfers after loading a game.
