Adam Reichold 0d0fb04d50 Make QTreeView::expand/collapse check for ineffectual invocations
Added checks if item is already expanded/collapsed to
QTreeView::expand/collapse since the following computations
can be quite expensive. (This is useful when saving/restoring a
lot of item expansion state e.g. after a model reset.)
