[Bug] Interception music will not stop after combat

[Neo23]

Hi, I found a bug in the latest nightly (2015_01_22_1227). The geoscape
interception music won't stop after combat and is playing forever.

Also in the new music.rul file, there are missing entries for the new
random interception music files (commit Thu Jan 22 11:52:57 2015 feature).
Adding these like geo and tactic tracks, doesn't fix the problem above though.

I guess recent commits attended to dogfight diversified tracks used in tftd broke something. Gonna be fixed really soon.
