[gnome-control-center/wip/networking2: 74/101] network: Redo IPv4 address section

[Dan Winship <danw src gnome org>]

commit c5e0b9b95b5e52f7ed5efaeabd1308d71abc3cdd
Author: Matthias Clasen <mclasen redhat com>

    network: Redo IPv4 address section
    
    Hide the address list entirely unless the mode is manual.
    Turn the + row into an inline toolbar. Make the delete buttons
    insensitive if there's only one row. Based on review feedback.
