The activity should keep its state in the journal updated. Of course,
this can be very expensive, so right now the data is saved at close
and when another activity gets the focus. At some point we'll want to
save periodically, but activities will need to grow a way of telling
is their state is dirty (and probably how much dirty).

This will get a you a very simple activity that does just that:
