changed: when there is reqtype:json parameter and there is not set request.ajax_serializer

then we are using a generic json serializer
changed: we are sending the application/json header when returning an json string
added:   to config: log_server_answer (default false)
         when true we put the whole string (server's answer) to the log file
added:   to Request: use_200_status_for_not_found_and_permission_denied
         if this is true then if the server http code would be 403 or 404
         then we return 200 OK (useful when using ajax)
changed: System::RedirectTo() methods take as the last parameter: use_reqtype
         if this is true (default) then reqtype:type parameter is automatically added to the redirecting path
