[Matthias Clasen <matthiasc src gnome org>]

commit c1246f41c03d755541a5a12779c9f282c9936528
Author: Matthias Clasen <mclasen redhat com>

    Add a new shopping list tile to the recipes page
    
    This shows the shopping list prominently on the landing page.
    
    The actual shopping list is still a placeholder.
