ToolButton: add 'icon_name' as a GObject property SL #3658
ToolButton: add 'icon_name' as a GObject property SL #3658

Sugar ToolButton inherits from Gtk.ToolButton but is not overwriting
'icon_name' property.  So 'icon_name' can be passed to the constructor
of Sugar ToolButton but the result is different than setting it via
ToolButton.props.icon_name.
