Import vorbisgain-0.37. vorbisgain-0.34 was in pkgsrc-wip.

Vorbisgain calculates a percieved sound level of an Ogg Vorbis file using the
ReplayGain algorithm. VorbisGain then stores in the comments (tags) in the
file a suggestion on how the volume should be changed during playback, to get
a uniform sound level.
