Berthold Stoeger 9829e49815 Dive list: move dive-selection code from filter to list
After invalidating the filter, the dive-selection was modified to
ensure that at least one dive is selected. This was done in the
filter code, but it seems preferrable to do this in the dive-list
code, which has direct access to the selection-model.

Therefore, move the code from MultiFilterSortModel to DiveListView.
While doing so, split the code in DiveListView into more functions to:
1) Get the index of the first dive (if any).
2) Select the first dive (if any).

This allows a distinct size reduction of conditional compilation
in MultiFilterSortModel (accesses to MainWindow are not possible
in mobile code).
