[Marinus Schraal <mschraal src gnome org>]

commit 1fbd4dbc03131b4183f2eab6a2b47eb5a7b971a4
Author: Marinus Schraal <mschraal gnome org>

    Rename items-selected property
    
    HeaderBar, SelectionBarMenuButton and SelectionToolbar have the
    items-selected property, which has identical purpose as the new
    selected-items-count property used in other widgets.
    Rename items-selected to selected-items-count for the given widgets.
