[WIP] Views cleanup

A long overdue cleanup of the views directory.

Amongst general cleanup and renaming, the following changes are particularly noteworthy:

 * c54a08d5495a19f1b9009a7f6a21ef128504bc9b adds a small helper app under `test/views` that lets you easily render views with dummy data. 
 * 7c7256c8f92d9e3bcb5c43734ba9cc80d6f11c5e introduces a new piece of middleware that lets static pages like `tou.html`, `privacy.html`, and `vpat.html` extend a layout so they won't get out of sync with style changes so easily.
