This patch adds a couple of useful functionality to mpg321, a free mpg123 clone by Joe Drew. It applies cleanly against version 0.2.10.

Changes against mpg321 v0.2.10:

• loop the hole playlist (v0.1)
• start playback at specified position of playlist (v0.1)
• fork to background (v0.1)
• no output in remote mode (v0.1)
• recursive scan of directories (v0.2)
• don't stop on file open error (v0.1)
