VNC AuthProxy runit script

These commits resolve #3 by adding a runit script to the default cookbook. 
You also need to either

1. <code>include Serverspec::Helper::DetectOS</code>
2. use <code>require 'spec_helper'</code> and remove the other require/include lines.

Number 2 is probably the better option.

You can make sure your tests pass with <code>kitchen test default</code> which will run these tests on both ubuntu and centos.
