AI: Change ground attack to fire all ordnance

[PatrickAWlson]

Currently the AI takes its own sweet time when performing ground attack.  It leisurely selects a target, attacks, circles, selects another, until all of its ordnance is gone or the timer runs out.

 

Please either alter the AI or allow the mission designer to tell the AI to drop/fire everything in one pass.  This would allow mission designers to make more effective use of bingo ordnance command and allow the planes to get the heck out of Dodge before AAA shreds them.
