fix network disconnect (SL#1608, SL#1802)

User interface changes:

- enable the disconnect button on the access point menu in the
  neighbourhood view, (rather than the button doing nothing),

- fix the disconnect button on the wireless device icon in the frame
  so that the disconnection remains effective [1], (rather than
  disconnecting and then reconnecting automatically),

Based on a patch by James Cameron <quozl@laptop.org>.
