Support basic rich text formatting using MarkDown (CommonMark?)

[nekohayo]

MarkDown has taken pretty much all the web by storm over the last 5-10 years, and it's a great way to allow users to have some basic text formatting capabilities without the pitfalls of pure HTML. GitHub/GitLab/Discourse/etc. are great examples of its usage potential.

It would be nice if BW could parse markdown at least for profile description fields, and ideally for messages too. The commonmark flavor would probably be plenty enough for BW. Being able to use real bulleted/numbered lists, bold, italics, and occasionally cleanly-written hyperlinks, would make my profile much more pleasant to read visually, compared to its currently raw and unparsed form.
