Many improvements

This release brings many improvements, like first_line_match, support for HTTP major versions without a minor like HTTP/2 and recognition of more media types for xml and json body highlighting. Plus a workaround for \r not being stripped out by bat and thus causing highlighting to not work properly. Many thanks to @scop.

• Plain Text
• JSON
• HTML
