[gnome-shell/wip/aggregate-menu: 47/59] network: Make the VPN rewrite "generic"



commit ad6549334eba2870c46aa6851704c2eba3163655
Author: Jasper St. Pierre <jstpierre mecheye net>
Date:   Tue Jun 11 20:13:37 2013 -0400

    network: Make the VPN rewrite "generic"
    
    Use the same infrastructure for other devices. For now, this removes
    almost all the functionality of the Wireless connection menu. We'll
    add it back in a later commit.
