Add delay to enemy CAP spawns

[Jeremy Smitherman]

At least to give our support folks a chance, lets add a 5-10 minute delay or so before enemy CAP can spawn.

I'm not 100% on board with this...maybe we delay the spawn of 90% of the CAP and just leave the MiG-31's alone? I've always enjoyed having to scramble and get off the ground to make sure that the AWACS/Tankers don't immediately get shot down. IIRC it usually takes the 31's about 15-20 min to get to the point that they're firing missiles.

Thoughts?
