Allow for the rendering of Mermaid flow charts in content

see also #90

This is currently now supported by including the script and initialising mermaid on page. Eg:

<script src="https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.min.js"></script>
<script>
    mermaid.initialize({startOnLoad: true});
</script>

<div class="mermaid">
  graph TD;
    A[Start] --> B[Process]
    B --> C[End]
</div>

Just note that free blogs can’t include or run JS for security purposes.
