Added Bind IPv6 rekord creation support
TODO:
	- handle __base6__ when checking IP
	- add IPv6 MX, NS, AAAA etc to DNS templates
	- automaticly add AAAA when creating domain
	- Domain's apache/lighttpd config creation
	- IPv6 PTR record?
TODO IPv6 Global:
	- Enalbe kloxo to listen on IPv6 (hint: hypervm is ready for that)
		- upgrade sbin c sources
		- change kloxo ligthy config
		- php listen on ipv6 socket
It is highly unlikely that I'd do this, just wanted to help with summing up.
Readded TTL support
