Christian Ehrlicher ba2f3a156e QTreeView: recalculate row heights in hide/showColumn() 
When calling QTreeView::hideColumn() the row heights are not
recalculated. This can lead to rows which are unnecessarily high due to
hidden columns may contain large (e.g. multiline) content. The same
applies to showColumn() - there the row might be to small.
Hiding columns directly via QTreeView::header()->hideSection() is not
covered by this patch since QHeaderView has no way to inform about
newly shown/hidden sections.

Task-number: QTBUG-8376
