feat: add 'edit-date' support to qt client (#1322)

edit-date got added to the backend in 3.00, but I never finished adding
it properly to the Qt client. This PR rectifies that. When a torrent is
edited, the Application and DetailsDialogs will re-query the backend to
update the torrent properties that are needed.
