IPv6 support added!

So, I updated things behind the scenes of STiBaRC, and added IPv6 support! Not that that means anything to any of you, but that just means STiBaRC is ready for the future of the Internet! Whenever IPv4 is phased out. Next to come is likely the profile pictures, which me and Ogelbeh have been planning. Then probably the Windows and Android app. Those will be announced on their respective release dates. Happy 'barcing!
