    datepicker: Only popdown on calendar double click
    
    Don't popdown the popover which contains the GtkCalendar on the
    "day-selected" signal, as this is also emitted on each time you change
    the month/year.
    
    Instead, use the "day-selected-double-click" instead, which is a better
    fit.
