* Added tests and code to verify that the a stumbler bundle will not
  exceed MAX_WIFIS_PER_LOCATION and MAX_CELLS_PER_LOCATION
* Updated mozstumbler.Log to use System.out.println so that logs don't
  show up on a single line during test.
* Changed allowed exception in mozstumbler.Log so that any Exception
  type is allowed, not just IOException
* Removed test specific code in WifiScanner
