BIND - add support for IPv6 reverse zones

Add a supplemental checkbox to "Reverse Zone" which further qualifies the reverse zone as an IPv6 reverse zone.
The resulting zone name will be *.ipv6.arpa rather than *.ip-addr.arpa

This change was originally submitted by jozemlakar@2b4e808 for Bug #4553
