    window-slot: Stop using flags parameter for history navigation
    
    The feature that allows opening a new window from the history popup menu
    by middle-clicking hasn’t been working for three years, since the flags
    parameter in nautilus_window_back_or_forward() is not honored. In some
    places it’s used inappropriately, so it’s better to just drop the code
    and rethink the approach if such a feature is desirable.
