Icecast relay

Figured out how to run Icecast in single-broadcast relay mode, leeching live audio off of Spark's server and distributing off of mine. I'm wondering how obnoxious of a set up we can get if we run slaved mode...

In any case, the single-broadcast relay is quite simple. Just uncomment/edit the example included in the default icecast.xml and point it at your icecast source of choice. No additional configuration is needed for the source.
