Proxy connection

[IDragonfire]

Sometimes people are connected over proxy, but an direct connection should exist. If they rejoin most of the time they directly connected (direct or direct throught NAT)

I could restart the connection if two people aren't directly connected, but I'll keep it this way for now to keep it simple. If only few and not most connections are using a proxy instead of a possible direct connection it's fine I think.
