Ipv6 can now be supported on Windows as well as on UNIX.
Loopback address constants are used when connecting the c-side to the erlang-side over local socket API avoiding getaddrinfo problems, and the {ip, loopback} option is added as a listen option on the erlang-side. Also cleaned up the TIME_STAMP contribution.
