Add support for mermaid.js diagrams

[dohliam]

This script adds support for rendering mermaid.js diagrams using the mermaid.ink API. Details can be found on the wiki page for the script, and there are a number of example diagrams here to show the results.

As noted on the wiki page, this should be considered a temporary workaround until full mermaid support becomes available, but it works reasonably well in the meantime.

Ah, nice. Thank you. Something like that was on my todo list, but I wanted to attempt to add the mermaid library directly as javascript (like it was done with https://github.com/qownnotes/scripts/tree/master/markdown-it) and try to generate an SVG locally and render that.

Maybe you want to add your integration for QOwnNotes at https://mermaid-js.github.io/mermaid/#/./integrations? 😉
