Move "recurrence" control to the bottom

[Cito]

In the "create or edit task" dialog, the "Recurrence" control is the first of the date controls, even though it is used very rarely. Usually tasks only have a due or scheduled date. So I suggest moving this control to the bottom, behind the "Start" control.

A concern about this is that lots of users will have in their muscle memory to tab forward a certain number of times, to reach a particular field, like Due or Scheduled. Re-ordering the fields will break that muscle memory, so should not be done lightly.
