bugfix - updating diagnosis when auto-requesting new tests requires reversion of request status from complete; import_xtr_96_data.tt tidy for consistency
simplified previous change to secure email; ngs_myeloid_screening.pl generates list from Perl array to save forgetting to put commas in correct place in query
modified previous change to enable user with secure address to email - given lowest priority over contacts.lib entry and generic email address (as used by UCLH)
for UCLH: arranged sort order of previous records by registration date then lab number - done by Perl sort function as RDBO forces t1.id 1st if using DATE(requests.created_at) in sort options
adapted admin clinician edit function to update hospital_department_code as well as is_active fields - previous is_active-only function broken on multi-location entries
