Merge pull request #3729 from reaperrr/ts-mod-improvements

TS mod improvements
added support for weapon launch sound effects
fix crash because of typo in c17 sequences
added support for nuke launch sound to confirm strike

separated into IncomingSound = "nuke approaching/detected"
and changed LaunchSound into "nuke lauched"

also nuke with small L .aud in cnc rules looks like a typo
split nuke announcements based on ally (and observer) / enemy

instead of me / everyone else
added "enemy planes approaching" EVA notification from demo.mix
play launch / incoming sounds in air strike power, too
