Feature: Correctly render Markdown content

[mgcm]

Message events may contain content where the body has text with Markdown markup. Some clients will include a formatted_body that includes the resulting HTML, if format with org.matrix.custom.html is set.

When available, we should correctly render Markdown content in the timeline. Element X iOS does this by creating AttributedStrings from the HTML.
