[icecast] Keepalive/last 10 songs list

[matthew at epiphanycorp.com]

Thanks to Robin and William for their keepalive scripting fu. Icecast/IceS are very crashy, and this script has worked pretty flawlessly for me. I also added some stuff to build a list of the last ten songs played. 

I'm using the version of the script that checks in the stats.log file for the source every two minutes. While it's doing that, it also figures out the currently playing song, and adds it to a list of the last ten songs played, a text file called 'songs.log.' I use PHP to parse this text file into a Web page for my site.

There's probably a much better way to do this, but it seems to work pretty well for me.

Thanks again, y'all.
