/SET resolve_prefer_ipv6 - should we prefer IPv6 or IPv4 addresses in

Browse source 
host name resolving. /SERVER ADD: added options -4 and -6. Fixed crash
at startup if server didn't have chat network set. "Connecting to xxx
[ip]" is now displayed before calling connect(), so if it fails we'll
still get the IP it's trying to connect to.
