The current daemon script for icecast does some odd things in terms of syntax, e.g.

[ ! -z $(getPID) ]

This is unreadable at a glance and doesn't subscribe to the /bin/bash shebang. I've rewritten the script to address this and simplified the logic as well. I don't actually use icecast, but I verified that this new script does properly start, stop, and restart the daemon, and as the proper user.
