Hack: store/restore font name box mru entries

When a LibreOffice window with a FontNameBox control is closed the
list of mru entries for the control is stored in a file,
discarding the previous saved entry list; when a document is opened or
created the last saved mru entry list for the FontNameBox control is
restored.
