UPnP doesn't work after /restartserver

when issuing the command /restartserver from RC, i see a server message in the dos window, [UPnP] Forwarded port (number) to (ip address) and the number and ip are appending itself instead of just using the initial string value.

For example, if your port was 14800 when the server started, on /restartserver it is 1480014800. Same with the ip.

Fixed in SVN. Thanks for reporting it.
