IPv6 support

[pschmiedel]

With many ISPs using DS-Lite, it would be nice if the game natively supported IPv6 for multiplayer. I'm currently tunneling IPv4 through an IPv6-VPN, which works, but is a hassle to setup for friends. Would be much nicer if they could use my IPv6 address / dynamic hostname.

I think we already support hostnames, no clue if it will work with IPv6 or not

We already support IPv6

Ok, it doesn't seem to work for me. I keep getting "Connect: no connection could be made because the target machine actively refused it". I've tried:

• different IPv6 formats (including ::1)
• a dynamic hostname
• setting the "Bind Address" in the .ini file to an IPv6
• disabling the firewall
  I'm on Windows btw.
