jabber init script

Well, I finally got a jabber server set up on agenteight.com.

In the process, I discovered that it’s a lot safer and more stable to run each transport (the piece that lets you talk to other IMs) in a separate process.

This makes management a little hairy, though, so I whipped up an init script for SYSV init style UNIXes that I think works pretty well.
