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

bugfixes: remove newly-renamed lab-test from screening map; remove trailing commas from query

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

full path to git for cron; changed dir to HILIS4 home so git commands work

genomics_xml.pl timestamps errors and also appends HILIS4 app version number to log file

removed invalid xml participant id entry 'UNKNOWN' if request unscreened

simplified generation of participant id - moved patient_case_id lookup into main requests query, skipped patient_case_id field when creating %required_fields; updated genomics.t so tests pass

genomics participant id only created/updated if record screened and unit number still at default UNKNOWN, previously had to lookup unit number every time

patched genomics_xml.pl to update unit number with participant id at any time, not just within of screening, in case of script error on 1st run after screening, in which case opportunity for unit number update lost

new additions to ngs_myeloid_screening.pl

bugfixes: don't skip request if validation fails for genomics.t; can't use content_contains on string with line-break

bugfixes a) auto-vivification in genomics_xml.pl, b) auto-vivification didn't cause validation failure in xml_validate.pl as params validated after xml created - changed to same order as in genomics_xml.pl; applied same fix as genomics_xml.pl to return value from validate_params() in xml_validate.pl

bugfix: uninitialized value warnings on empty retrieved storage params

bugfix: recent change 'min' to 'mi' jQuery watermark required corresponding change in remove_jquery_watermark()

bugfix: localised block to prevent 'variable masks earlier declaration in same scope' warnings
