Add support for Wagtail integration

[paltman]

I think we can leverage all the work done in this app and allow for creating blog posts within Wagtail by supplying just a couple classes.

I'm relatively green to Wagtail though so I might be underestimating the effort or misunderstanding the viability of such an idea.

Not sure if it's a good idea, but happy to help evaluate!

If you want a blog already for wagtail there is coderedcms

@bastianhilton Thank you for pointing that out. We will take a look!
