Add support for XEP-0393 message styling 

Fixes #1083

Directives are rendered as templates and their bodies are MessageText instances.
We thereby achieve the necessary nesting of directives (and other rich
elements inside directives) by letting each directive
body render itself similarly to how the whole message body is rendered.
