[Matthias Clasen <matthiasc src gnome org>]

commit 7ecf5c43e0786969eb1b392a9ee4f80e1e521bf1

    Add a selection mode testcase
    
    This shows what one currently has to do manually to get the typical
    selection mode with blue headerbar and checkboxes in list rows.
    The goal is to make this easier.
