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

added genomics NHS number validation; changed error log frequency -> percent

added percent col to monthly register_and_error_log; enabled reason for vial deletion for all vials, not just tyhose allocated to plate

register_and_error_log.pl converted to use tt for message
