net_wins.c is gone, winsock support merged into net_udp.c

net_wins.c is gone, winsock support merged into net_udp.c
numerous other cleanups/changes also done to net_udp.c (to try to simplify it, hopefully work better, that kind of stuff)
support for partial IP addresses has been removed (that is you say you can't simply type 'connect 1.123' and have it expand to xxx.xxx.1.123 where xxx.xxx came from your own IP address, however hostnames still work fine)
also the automatic changing of the hostname cvar according to internet hostname has been removed, so servers will be called "UNNAMED" if they don't set it, rather than using their internet hostname
