Fixes: QTreeView font change regression if there is an application stylesheet

The way font propagation work has changed since 4.4: When there is a
stylesheet enabled, font does not propagate.
So when settings a font to the QAbstractItemView, the viewport font will
not change, and hence no QEvent::FontChange on it.
So catch the QEvent::FontChange in QAbstractItemView::event in addition
to QAbstractItemView::viewportEvent.   (we seems to use the view's font
everywhere anyway)
