QStyleSheetStyle: add new property to QPushButton: icon
There is currently no proper way to change the icon of a pushbutton from css. But there is a need for doing so (QTBUG-2982), and the typical work-around is to instead use the css property 'qproperty-icon'. But setting qproperties from the style is not a good idea in the first place, since it modifies the state of the widget it draws. Moreover, such properties are only set once (in QStyle::polish()), and will not have any effect on pseudo states, like hover. To close this gap, this patch will add a css property 'icon' that can be set on a QPushButton. This property will follow normal css cascading, and respect pseudo states, equal to any other css property. [ChangeLog][QtWidgets][QStyle] You can now set the CSS property 'icon' on a QPushButton to override which icon to draw.
