Fix selection madness in ArchiveTreeWidget

First try on fixing this. Still use
QItemSelectionModel::selectionChanged, but ignore the QItemSelections.
Use QItemSelectionModel::selectedRows() instead and compute the
seriesPartIds on every change. Hopefully this guarantees having valid
QModelIndexes all the time.

This fix also obsoletes the quite awkward function
SeriesTreeWidget::mapToSource(). Make the QSortProxyModel of
SeriesTreeWidget available through SeriesTreeWidget::seriesProxy()
instead.
