ATTN Mike!
make install now installs the xsl files in pkgdatadir ($prefix/share/icecast) web
and admin directories, and builds icecast.xml accordingly. icecast.xml is now
installed in $sysconfdir/etc, and IMHO icecast should attempt to find a config
file there, and only demand one on the command line if it can't.
