Vagrant, Virtualbox, & Ansible provisioning

### Why did Ben do this? ###
@slylth has been working with vagrant, virtualbox, & ansible. I decided it might be fun to try get up to speed on them, and provide for easy vm creation/destruction for the upcoming hackdoc while at it. This code, and the accompanying README.md, should make bringing up (and destroying) a local virtualbox vm of reason effortless. I assume a more experienced ansible playbook admin would have suggestions on how to clean up and structure my playbook.yml, but hopefully this is an acceptable start.

### Benefits ###
* Newcomers can have a local reason install up and running without knowing very much about the install process and dependencies
* more seasoned developers can create and destroy virtual reason environments about as easily as eating bacon and chocolate
* potential building block for future management of deployment to production environments very quickly and effortlessly
* and more...

### Note ###
Installing all of the required packages in the virtual machine takes a bit.
