When a bib record is opened in the MARC editor, fields that
can be put under authority control now have a link button at
the end of the subfield list. When clicked, this opens
a dialog box that, for now, allows:
* creating a new authority record based on the bib heading
* creating a new authority record and launching a secondary
MARC editor.
