Comms menu: Swap "request launch" and NVG/HMD items for SC

[Nealius]

Comms selection for "request launch" should be F8-->F7 so as to be compatible with VoiceAttack and the F-14. F7 was "request launch" prior to the helmet mount option, so now VoiceAttack users must have two separate voice commands for the same action across two aircraft, when the Hornet's helmet mount options selection could simply be moved to F8 instead of F7.

Update: With the F-14A, it appears to have a new option in F8-->F7 as well, shifting things over unpleasantly. I guess this is now an issue for the F-14B to be standardized, and not something for the Hornet specifically.
