Updated Spec Helper
Updated Spec Helper

* Added color to the output
* Added an alias example so I can use `describe_recipe "ark::default"`
* The alias automatically loads the shared_context that gives me some
  helper methods like:

  ** chef_run - default run with no node_properties
  ** node - the chef_run's node.
  ** node_properties - blank, but can be overriden when needing to change the platform
  ** default_cookbook_attribute - lets me check for an attribute on the node
