Clean up Production

This demo was getting a bit weighty, I'm paring it down because
I don't really want a simple demo to get difficult.  Plus, it's my
repo and I'll do what I want to...
Add initial Hieradata to the production environment
Add a base environment.conf

This file configures directory environments, as opposed to static
puppet.conf-style environments.
configure_directory_environments script

This script will configure puppet.conf to use directory environments.
