Set the appropriate mime response headers for negotated type-map
  Body: responses.

  wrowe's review;
    My earlier concern doesn't apply.  Type maps have always required the
    author to be explicit in all header fields to be negotiated; if the
    headers aren't given in the type map file the resulting redirect
    (for non-body maps) is broken anyways.  As to my other concern, the
    charset should only exist if the Content-Type was given.
