[Feature Request 2.8] Add no-loop option to jukebox

[LawfulDickish]

Currently, music will always loop from the beginning when it ends, or between a specified start and end point provided by a .txt file, unless the music.yaml for the server specifies it as non-looping, in which case it will never loop.

However, sometimes a user might want a looping song to only play once, end more naturally than just manually shutting off the music, or play the track's ending sequence which is cut off by the custom loop points. For these cases, an option to force a song to ignore any looping points should be added among Synchronize and Fade In/Out
