It was possible to define a delay in days on activity type
to reschedule next activity. It is now possible to specify a unit
(days, weeks, months) and a starting point for the delay
(as before, from the moment when the new activity is scheduled,
but also after the deadline of the previous activity).
We realy need to have all javascript action triggering a done
and schedule next to call the python corresponding method on
activities. A part of the work have been there but some
cleaning could still be done in activity.js.
