Update to 0.13
    
    - New upstream release 0.13
      - Documentation corrected to demostrate how to properly override the
        configfile method to provide a default from the consuming class, without
        having to redefine the attribute itself
      - If MooseX::Getopt is installed, the configfile attribute has the Getopt
        trait applied
      - The configfile attribute is now a Path::Tiny, not a Path::Class (coercions
        from strings are still supported, and now also from any other type that has
        a string coercion)
      - Allow configfiles called "0"
      - configfile value now passed through to new()
      - New _get_default_configfile method added, which consumers can override to
        provide a default value without having to redefine the attribute itself
        (via CPAN RT#79746) - PLEASE READ THE DOCUMENTATION if you override the
        configfile attribute!
      - Allow clean composition into a role, without requiring an -exclude
      - Bump prereq version for MooseX::Types::Path::Tiny to ensure a broken
        version is not installed
      - Warnings tests bypassed during installation
      - Repository migrated from shadowcat to the github moose organization
    - This release by ETHER -> update source URL
    - Switch to Module::Build::Tiny flow
    - Classify buildreqs by usage
    - Package upstream's CONTRIBUTING, LICENSE and README.md files
