Error gracefully for empty mappings

parser.py fails when the RAML file has an empty mapping, e.g.:

/foo:
  get:
    responses:
      200:
        body:
          text/plain:

the following traceback occurs:

AttributeError: 'NoneType' object has no attribute 'get'

This is ugly and shouldn't happen :)
