Subject: [PATCH] Add --due-date and --clear-due-date to the edit command

The edit command could change a reminder's title and notes but had no way
to change its due date, even though add supports --due-date. This adds:

- edit --due-date/-d <date>: set a new due date, parsed with the same
  natural language parser add uses
- edit --clear-due-date: remove the due date entirely

Setting a new due date replaces any existing alarms, and adds an absolute
alarm when the parsed date includes a time, matching add's behaviour.
Clearing the due date also removes existing alarms.

--due-date and --clear-due-date are mutually exclusive, and edit now
accepts a due date change alone (previously it required new text or notes).
