Update to 0.13
    
    - New upstream release 0.13
      - Removed file readability check (GH#4, CPAN RT#99055)
      - Now supports @INC hooks (GH#6)
      - Now filters out filenames starting with a dot (GH#7)
      - Now uses strict (GH#8)
      - Fixed CPAN RT#122016: test/ files show up in metacpan
      - Module::Find now uses @ModuleDirs (if specified) for loading modules
        (CPAN RT#127657); previously, when using setmoduledirs() to set an array
        of directories that did not contain @INC, Module::Find would find the
        modules correctly, but load them from @INC
