Title: Make (un)abbreviating journal titles also work on the journaltitle field

I've (i) added the toggle button to the "journaltitle" field editor
and (ii) made the abbreviate/unabbreviate actions change both the "journal" and "journaltitle" fields.
The latter might be a bit simple-minded -- should the field to consider depend on whether Biblatex mode is actually turned on?
