GitHub's CommonMark Markdown renderer is now safe by default

This is the result from a library I built this monday called safemd (https://github.com/Hultner/safemd). It didn't gain much attraction on HN but stayed on top 3 lobste.rs (https://lobste.rs/s/szw60m/safemd_markdown_renderer_focusing...) frontpage items for a full-day.

This caught the attention from kivikakk/Ashe, the primary maintainer cmark-gfm (GitHub's CommonMark renderer) and ultimately led her to change the default behaviour in their upstream library.

I am humbled by the fact that my little project managed to get the default behaviour changed and as a strong believer in safe defaults I see it as a much greater success then I ever think my project could have achived.
