Berthold Stoeger e46b1e88d9 Selection: move translation of indexes to filter model
The DiveListView caught signals from the DiveTripModel
with the corresponding indexes. However, the DiveListView
is actually connected to the MultiFilterSortModel and
thus has to translate the indexes.

Instead, catch the signals in the MultiFilterSortModel,
transform them and resend. Let the DiveListView get
its signal from the MultiFilterSortModel.

Yes, this makes things less efficient because there is
an extra signal. On the upside, the makes data-flow much
more logical. Selection will have to be fixed anyway.
