Reverse zones: name hosts from other views' records; search and bulk dismiss for long lists

A reverse zone's fill (and fill-ptr, the missing-PTR counts) names an address no record of its own view uses from another view's record, so an internal reverse zone can give the PTR of a host only external has an AAAA for; New reverse zone with a view chosen lists those addresses, marked. Automatic suggestions stay per view.

For hundreds of addresses: the New reverse zone list has a search; on the Zones page the public addresses fold away, have a search, show 25 at a time and Dismiss these N dismisses everything a search found in one change (reverse.dismiss takes prefixes; --dismiss takes several).
