Upnp router configuration

Hi,
I tried ZeroNet on a computer, and it opened Upnp ports on the connected router
Then I tried ZeroNet on another computer behind the same router
and it was not able to open ports for this other IP address,
so I was not able to distribute the network,
so I removed the old UPnP configuration on my router,
and I reloaded ZeroNet, and it opened the ports of the new IP address.

;)

Hope it helps to improve the software

Start with src/util/UpnpPunch.py, especially _parse_for_errors at line 139 and _send_soap_request at line 171, then review the reported UPnP failure when a second computer uses the same router. Reproduce the two-computer setup if possible and verify that the failure no longer produces an unhandled ExpatError and that the port-mapping result is reported correctly.
