Initial project setup

* Based on "alchemy" scaffold from Pyramid 1.5.1
* Use a requirements.txt and a dev requirements.txt and link these to the setup.py
* Switch out Chameleon ZPT with Jinja2
* Use Gunicorn instead of Waitress
* Cleanup unneeded static files that come with the Pyramid scaffold

This is just a starter, much more to come later!
