Quick hack to use ganglia in a cluster with a non-multicasting

Quick hack to use ganglia in a cluster with a non-multicasting switch. Doesn't scale too well, usable on a 24 cluster though. Idea: listen to port _serverPort (8666 as default) for gmetad's request for XML data and when connected, gather XML from individual nodes from port_gmondport and serve it to gmetad.
