Added ipv6 support. Listening processes us hybrid dual stack feature of OS to simplify implementation and use a single listening socket. Works with both TCP and UDP. Parasol working. geoIp also updated and ready for IPv6. Should be invisible to most users, while providing connections via ipv6 where available. Supports both ipv4 and ipv6.
