* sloodle_error_code - 
* Author: Paul Preibisch
* Description - This function sends a linked message on the SLOODLE_CHANNEL_ERROR_TRANSLATION_REQUEST channel
* The error_messages script hears this, translates the status code and sends an instant message to the avuuid
* Params: method - SLOODLE_TRANSLATE_SAY, SLOODLE_TRANSLATE_IM etc
* Params:  avuuid - this is the avatar UUID to that an instant message with the translated error code will be sent to
* Params: status code - the status code of the error as on our wiki: http://slisweb.sjsu.edu/sl/index.php/Sloodle_status_codes
