Vagrant

Add [Vagrantfile](http://www.vagrantup.com/) for development. This includes a bash script which provisions the virtual environment.

Although I could have used virtualenv, I chose vagrant because I didn't want to be playing around with my live ssh config file. To use,

```bash
$ vagrant up
```

The virtual environment lets you use storm the normal way while letting you modify the source in the /vagrant folder on the virtual box.
