Replaced any internal call to WGI_RESPONSE.write () by the associated implementation (i.e output.put_string (...) )
Added WGI_OUTPUT_STREAM.put_crlf
Renamed WSF_RESPONSE.put_response (a_message) as `send (a_message)'
WSF_RESPONSE_MESSAGE.send_to (res) is now exported only to WSF_RESPONSE
Now DEFAULT_SERVICE has to be created instead of inherited.
- This seems to be better for new user, and this avoid potential conflict and difference when inheriting between the various DEFAULT_SERVICE implementation.
- remember that DEFAULT_SERVICE, is mainly to help the user to build its very first service.
Use READABLE_STRING_8 as argument whenever it is possible.
Added WSF_RESPONSE_MESSAGE, and WSF_RESPONSE.put_response (a_response_message)
Now WSF_RESPONSE inherit from WGI_RESPONSE
