- small cleanup after #450
- whitespace cleanup
- use www.cpan.org; search.cpan.org is down and it just redirects us
  normally anyway.. (when downloading tarballs)
- update changelog
- version bump
- be explicit that cpan support only works under ruby 1.9 or higher.
  I tried to use Net::HTTP (instead of FTW) but the API is so fucked
  I gave up trying to do it.

  Hopefully this won't matter soon once I get to publishing omnibus fpm
  packages.
