Subject: Sync networking state between Sugar and GNOME #10532 (Gonzalo Odiard)

Case A: User disables the wireless and/or networking in
GNOME (nm-applet)

Case B: User does disable the networking in the Control
Panel in Sugar (includes wireless)

When the user uses the Control Panel to disable/enable
the networking we run rfkill and enable/disable as well
NM.
