add on_name_changed() virtual method to CairoWidget

Browse source 
If a CairoWidget does not a GtkRC-defined style, then changing its name does not trigger on_style_changed(). Since we want to use CairoWidget::set_name()
to trigger changes in the rendering of a widget, this is ... bad. Adding on_name_changed() provides a workaround for that.
