Uploaded my SRS implementation for courier to the web

As I wrote two days ago, I have written a small utility to do SRS 
forwarding with the Courier mailserver. The first small documentation 
for it has been finished, so I was now able to upload it to the web.

You can get the initial documentation on how to build and use couriersrs 
as well as the source package for it on http://xmpp.eu/couriersrs
