PR for issue #244.

As mentioned in the issue above, I checked out the public-ip crate to find a way to bind to a public IP. I added public-ip=0.2.2 to the cargo.toml.

I removed the usage of search_gateway and replaced it with public_ip::addr() which from the docs: attempts to produce an IP address with all builtin resolvers (best effort). This function will attempt to resolve until the stream is empty and will drop/ignore any resolver errors.

Thanks for the PR!

I wonder if you could retain search_gateway and use public-ip as a backup for when UPnP fails?
