The icons of items which are "cut" are shown faded in the view. The
"is cut" state of the widget representing an item is updated if the
clipboard contents change. Before this commit, if the sort order was
changed however, then each widget kept the "is cut" state of the item
which had been shown previously at its position.

The solution is to update the "is cut" state also if any of the
widget's data change.
