    files-view: Support keypad in zoom in/out accels
    
    The view can be zoomed in and out by pressing the + and - keys on the
    keyboard while holding the Ctrl modifier key.
    
    However, pressing the look-alike + and - keys from the numeric keypad
    doesn't work as an alternative, as one would expect.
    
    Add these keys as alternatives for the zoom shortcuts, like GtkScale
    and GtkTreeView already do in similar cases.
    
    Closes: https://gitlab.gnome.org/GNOME/nautilus/issues/1349
