        (-[WebDataSource _MIMETypeOfResponse:]): Added. Works around

        with a MIMEType of application/octet-stream and a Content-Type header
        starting with text/plain and returning text/plain as the MIME type in
        that case.
        (-[WebDataSource _responseMIMEType]): Added. Used to get the correct
        response MIME type.
        (-[WebDataSource _isDocumentHTML]): Changed to use _responseMIMEType.
        (-[WebDataSource _makeRepresentation]): Ditto.

        (-[WebResource _initWithData:URL:response:MIMEType:]): Changed this
        method to take a MIME type instead of extracting it from the response,
        so that WebDataSource could pass the correct MIME type.
