Update Archive-Tar to CPAN version 1.70

  [DELTA]

  * important changes in version 1.70 15/11/2010
  - Add ptargrep utility courtesy of Grant McLean

  **  I think I found everywhere that needed updating
      by grepping for 'ptardiff' and adding where needed.
      This stuff is definitively not intuitive.
