WidgetPath.appendWithSiblings

Appends a widget type with all its siblings to the widget hierarchy represented by path. Using this function instead of gtk_widget_path_append_type() will allow the CSS theming to use sibling matches in selectors and apply :nth-child() pseudo classes. In turn, it requires a lot more care in widget implementations as widgets need to make sure to call gtk_widget_reset_style() on all involved widgets when the siblings path changes.
