activated apparent_sender = no-reply@hmds.info to avoid rejection of messages from non-existent domain; adapted yearly register_and_error_log.pl to use same tt as monthly version; a failed cytogenetics result is now more verbose so cytogenetics_failed query needs to look for 'failed' as an rlike
switched to Local::DB for live to use insert_or_update method; moved update_patient_demographics to own sub due to increased complexity - need insert_or_update method; bugfix for initial cml patients query - needs additional 'undef' on pd.status or has same effect as inner join instead of left join
