Realistic authentication profile data

[encratite]

The native connection or proxy data should be used to determine the outgoing IPv4 so it can be properly set in the authentication profile. Right now we are just using a pre-determined value specified in the configuration which makes little sense when you are connecting through a proxy like Tor where you end up with random IP addresses all the time.

Right now Riot don't check this value but it's better to be prepared.
