Update CGI to CPAN version 3.59

Update CGI to CPAN version 3.59

  [DELTA]

  Version 3.59 Dec 29th, 2011

  [BUG FIXES]
  - We no longer read from STDIN when the Content-Length is not set, preventing
    requests with no Content-Length from freezing in some cases. This is consistent
    with the CGI RFC 3875, and is also consistent with CGI::Simple. However, the old
    behavior may have been expected by some command-line uses of CGI.pm.
    Thanks to Philip Potter and Yanick Champoux. See RT#52469 for details:
