Holidays

- Renamed all holiday files to include a locale, rather than just
  a country code.
- Enhanced update-holidays.pl add-on script to support regions,
  provide better error handling, error on missing Perl module,
  warnings on unavailable data, and help text.
- Updated documentation accordingly.
