Make AAF friendly to NATO

Might fix people in the hellcats showing up with red tags instead of
green ones.
Vehicle revamp + base tweaks

Based on some suggestions from the forums. Vehicles now include 1x
wipeout, 2x hellcat (armed), 1x hellcat (unarmed). Moved spawns of the
choppers to be all together (not on the auxiliary pads) and changed
barriers to be concrete instead of roadbarriers.
More base tweaks

Add numbers for the helicopter landing pads. Add barriers to all the
landing pads.
Update PBO

Includes (possible) fix for nato colors. Vehicle re-vamp. Lots of base
tweaks.
