Added lbsa71's http server changes.

So it now has a single http listener that passes incoming requests to the correct handler. This means that logins (in sandbox mode) now go through this listener, which for now is listening on the port you set in startup (default 9000). (This needs changing so that the http listener and udp server are not using the same port)
