Updated to use main download page not Google Code

* The version on the Google Code page is out of
  date and does not appear to be updated any
  longer.
* Switched the download recipe to use the main
  arduino.cc download page and searches for
  the first match with 'macosx.zip' in the URL
  (which hopefully will always be the current
  version).
* With Arduino.app v1.0.6 the code signature
  has been updated to comply with recent
  Apple requirement changes.
