v0.2.0

Changed

• Moved to html-validate v4 API.
• Splitted processing files and displaying reports:
  • Removed throwing errors in the main function.
  • Added format and failAfterError functions which can be used in pipeline.
    This way allows to print html-validate results for every file and (optionally) fail on errors after all files are processed.
    See the readme file for examples and usage.
