Implement a MarkDown field for TextFields in Event and Resources

[nmunro]

Implement a MarkDown field for TextFields in Event and Resources, this will allow for some rich text formatting for beter presentation of data.

Consider this: https://github.com/dmptrluke/django-markdownfield
https://pypi.org/project/strip-markdown/

This is also going to require CSS left alignment for text, so things like bullet points etc don't look weird.
