Fabric code for deploying the site to a vagrant box

These changes allow you to run a command to deploy the bugtracker site to a vagrant box. We can walk through the code.

Hopefully you could clone this branch, run `vagrant up` and then run `fab vagrant provision` and then `fab vagrant deploy`. After that hopefully you'd be able to point your browser to 127.0.0.1:8080 to see your site.




whoops, I forgot to add fabric and fabric tools to the dependencies!

``
Fabric==1.9.0
fabtools==0.19.0
