* Expose how we render the HTML _surrounding_ rich text content as an
extensible `layouts/action_view/contents/_content.html.erb` template to
encourage user-land customizations, while retaining private API control over how
the rich text itself is rendered by `action_text/contents/_content.html.erb`
partial.
*Sean Doyle*
* Add `with_all_rich_text` method to eager load all rich text associations on a model at once.
