Changeset 902 for trunk

First pass safety fence to help prevent "missing" forward records. If a
DNS entry is passed as an unqualified name, the A part of the A+PTR
metarecord gets dropped since there will be no match in the domain list.

This adds a setting, defaulting to enabled, to append the default domain
to unqualified names in the main rDNS field on add and update.
