0.14.0

Features:

• Allow view functions decorated with response to return a Response
  object or a tuple with status and/or headers (:pr:40).
• Allow view functions decorated with paginate to return a tuple with
  status and/or headers (:pr:40). The pagination header is now passed
  in the response tuple. Users relying on undocumented
  get_context()['headers'] as a workaround to pass headers must update
  their code to pass headers in the response tuple as well.

Bug fixes:

• Fix ETag computation when headers contain a duplicate key.
