HTTP: ignore "Content-Encoding: compress"

Currently, libcurl rejects responses with "Content-Encoding: compress" when CURLOPT_ACCEPT_ENCODING is set to "". I think that libcurl should treat the Content-Encoding "compress" the same as other Content-Encodings that it does not support, e.g. "bzip2". That means just ignoring it.
