Set metadata type attribute to :acceptance so that helper modules and…

… hooks can be set exclusively for acceptance specs without contaminating other specs in the suite. Closes #12

+Steak scenarios are just regular RSpec examples with their metadata attribute 
+`:type` set to `:acceptance`. That's useful if you want to make sure you 
+include helpers or set hooks only for your acceptance specs and not for the 
+rest of the specs in your suite.
+
+You'd do it this way:
+
+  RSpec.configure do |config|
+    # include MyHelpers module in every acceptance spec
+    config.include MyHelpers, :type => :acceptance 
+
+    config.before(:each, :type => :acceptance) do
+      # Some code to run before any acceptance spec
+    end
+  end
