Adding Vagrant for simple dev setup

Hey Yellrs, I added a Vagrant setup to help me learn the structure of this application while y'all were figuring out what needed to be done during the Hackathon. This removes the need to

Assuming you have Vagrant, VirtualBox, and Ansible installed (you van get these with brew), just run

    vagrant up
    vagrant ssh
    cd /cd server/yellr-serv
    pserve development.ini
    # navigate to http://192.168.50.100:5000/ on your host

I can also get some nice automation going to apply this to the actual server hosting the real application based off the same stuff.
