Ansible

Relates to willkg/richard#215

I kind of wanted to play around with Ansible & Vagrant anyways so this takes a quick crack at it. This is is based off my factoryboy branch, so once that branch is finalized this one will need a bit of rebasing magic applied.

Anyhow, it's a basic ubuntu / nginx / uwsgi setup. It uses the Dev configuration and doesn't do anything fancy with the DB so I'm sure there are some problems there. Getting the scripts to do fancy stuff like setup postgres and have the Dev role use that with some config is possible but I wanted to get this up here for comments first before getting too far along that path.
