Removed WGI_RESPONSE.write (..)

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
