Use parse_{time,duration}() where appropriate

Make use of these new helpers at various places. Note that this patch
implies a few behavioural changes:

* Short forms such as "23:" and ":45" are allowed when entering times.

* Durations always need to be prefixed with a plus sign ("+"), with the
  nice side effect that you can now use "+3:30" to declare an
  appointment that lasts three hours and thirty minutes (that's much
  more convenient than "+210").
