Changeset 108 for trunk

Add timestamp and location stub output in export_tiny() to

support tinydns' automagical recod-is-valid timestamp and
split-horizon DNS capability respectively (once the data is
provided in the database, and tools can manipulate it)

Export PTR records
Add stub space for "other" record export - note that due to

the way Net::DNS provides the data via rdatastr, we can't
(easily) reconstruct the real record data.
