Vagrant file

I use your app at work.  We wanted it to run in a controlled environment, so I threw it into a Vagrant VM.  We spin it up on a publicly accessible machine that runs VirtualBox and Vagrant during sprint planning, and spin it down during the sprints themselves when we don't need it.  Maybe you'll find it useful.

I committed my changes - a Vagrantfile and some simple Puppet code - to a branch called 'vagrant', so running this looks like:

~$ git clone https://github.com/gdamiani/Hatjitsu.git
~$ cd Hatjitsu/
~$ git checkout vagrant
~$ vagrant up
