(self, file_object, content_type=None, filename=None,
                 name=None, id=None, nr=None, label=None)
Add a file to be uploaded.

        file_object: file-like object (with read method) from which to read
         data to upload
        content_type: MIME content type of data to upload
        filename: filename to pass to server

        If filename is None, no filename is sent to the server.

        If content_type is None, the content type is guessed based on the
        filename and the data from read from the file object.

        XXX
        At the moment, guessed content type is always application/octet-stream.
        Use sndhdr, imghdr modules.  Should also try to guess HTML, XML, and
        plain text.

        Note the following useful HTML attributes of file upload controls (see
        HTML 4.01 spec, section 17):

        accept: comma-separated list of content types that the server will
         handle correctly; you can use this to filter out non-conforming files
        size: XXX IIRC, this is indicative of whether form wants multiple or
         single files
        maxlength: XXX hint of max content length in bytes?
