Provide scrollbar for large items

If an item does not fit into the available width/height a scrollbar
should be provided (e.g. typically this represents the horizontal
scrollbar in the details-view where the width can be larger than
the than the visible width).

Currently the interaction with the scrollbar is not implemented but
this will be a quite minor task in comparison to this patch.
