Remove wagtail

This should eradicate wagtail from the project.

While wagtail may be nice, our goals are to keep all things public, and
having things locked behidn a DB is congruent to that plan.

All in all, the django project only leveraged a single wagtail feature,
"richtext" which has been hacikly removed and will result in bad display
of however it comes up. But this is on homepage.html, which will be
removed and covered up with a static website, which means we should be
able remove homepage entirely from this project.

This reduction hopefully makes the monolith easier to understand,
maintain, and wield.

Wagtail integration (#17)

* Adds basic wagtail app to the website

* Renames lca_website to cms_pages for clarity; re-instates pinax-boxes until we remove them from the templates

* OOPS

* Just Enough Wagtail

* Removes the template view homepage from urls.py

* OOPS

* Makes the home page use a stream field

* Removes an irrelevant migration that I accidentally introduced.
