Adding Vagrant / Puppet support

Adds Vagrant / Puppet infrastructure. Sets up a Linux Ubuntu 32-bit 12.04 LTS image with
* Node.js v0.10.25
* Elasticsearch 1.0
* Python 3.4
* Grunt
* Forever

This configuration file does not yet attempt to load data into the local elasticsearch instance. It does launch the API via Forever.
