Berthold Stoeger a45c5faa8c Filter: update current dive if change hides current dive
When changing the filter-criterion and the current dive is
hidden, a new dive is made current. However, when a dive is
hidden because it was edited, it is still shown.

Make this consistent by also selecing a new current dive
in the latter case. Do this by comparing the current_dive
before and after calculating the filter. Since this is now
done in multiple places move this code to the ShownChange
class.
