agenda, capture and finder: what needs doing comes to you

GET /api/agenda gathers unfinished cards from every board that are late,
due within a week, or in hand, plus whether the diary has today; the
reminder mail and the agenda share one diary check. t opens it (and it
opens itself once a day when something is late or due), T writes today's
entry, the bar counts late and due cards, Ctrl-P searches every space,
and a document o made that is left empty is removed on the way out.
