Authority auto-complete for hymn texts, tunes

Description

The hymn text and tune edit pages need an authority input system much like that for persons. It should allow the user to designate the authorized version of the text or tune. It should also have an auto-complete feature much like that for persons. I suppose it would work by allowing a user to type in part of the text or tune name and showing all matches.
