v0.5.0

Version 0.5.0 adds the XHTML5 backend, as well as support for custom substitutions on paragraphs and delimited blocks.
Also, rendering on other blocks as also been greatly improved, thanks to better support for attributes.
Finally, source blocks can now be rendered with the Chroma syntax highlighter (using the :source-highlighter: pygments or :source-highlighter: chroma document attribute) and callouts are supported.

As usual, this version also includes its share bug fixes as well.

Huge thanks to gdamore and pjanx for their numerous contributions 🙌
