Increase airfield distance in Battle of Abu Dhabi.

Removes some of the low capacity airfields from the campaign now that
missions can plan longer ranges if needed.

This removes Khasab, Bandar Lengeh, and Qeshm from the blue side, so
blue no longer has any airfields on the peninsula.

The CVN has moved quite a ways west to make it a good platform for
attacking the area around Dubai, and to prevent it from being the
primary mission source (with a 90 aircraft limit, a *lot* of missions
can get planned there before other airbases will be used).

The LHA moves to near where the CVN was, making it a good platform for
early game missions. Once the LHA's 20 aircraft limit is exhausted, Kish
and Bandar Abbas will be the primary airfields early game. Bandar Abbas
is still close enough to source Hornet and Viper missions to most of the
area around Dubai. It's unable to reach Lar with those aircraft, but
Kish and the CVN can (as can captured airfields).
