Drupal installation, and any plugins that need to be written.
Simply install Vagrant (http://vagrantup.com) and run vagrant up. The SQL and Drupal admin passwords for vagrant instances are in
the puppet module, but should, obviously, not be used for publically
accessible machines.
The drupal_setup.sh script can be used to install Drupal, plus any
dependent modules. If we need to add more modules, we should add them
to that script.
