added: generating Content-Length header when text answer is sent to the client

added:   now we are able to use the html filter for the whole out_streams (when ajax is used the output is filtered too)
         splitted FilterCompressSend() function -- first we are making the filtering
         (after filtering we know the size of the content to send)
added:   to Compress:
         Compressing(const char * source, size_t source_len, BinaryPage & out_stream, int encoding);
changed: some refactoring in App
