switch zlib.output_compression off, as we cant calculate Content-Length header, if its on, doing our own Content-Encoding: gzip now (wont be necessary for Apache2.2 which fixes false Content-Length headers silently, but eg. Lighttpd cuts off content, if wrong Content-Length header specified

using md5 of real content for instance specific translations, cant use lang_ctimes for them
