Replace 'Scanning' text in Network Status Area with throbber

This CL:
* Removes the 'Scanning' text from the network list
* When scanning starts: Starts the throbber (which fades
  in), and fades the info button out. Clicking on the
  Throbber is the same as clicking on the info button.
* When scanning stops: Stops the throbber (which fades out)
  and fades the info button in.
