Use gUPnP to determine external IP address and control URL
21 months ago, Elliott Sales de Andrade

Use gUPnP to determine external IP address and control URL
This is based on the gUPnP example, but modified to use the async API, and its context manager to automatically check all interfaces.
Testing Done:
Opened prefs and checked that external IP was detected with a UPnP-enabled router.
