- fixed rt.cpan.org#63487 documentation error.

- fixed rt.cpan.org#61302, now croak if the config file
          parameter is a directory and directory include is not
          turned on.

        - fixed rt.cpan.org#60429 META.yml typo

        - added new option -AllowSingleQuoteInterpolation, which
          turns on interpolation for variables inside single quotes.

        - added test case for the new option
