bugfix - previous requests in screen, report, etc skipped any non-reported requests - fixed by making authorised_reports table a left join; fixed inability to delete trial & trial number in request edit - loads frozen data trial.id in absence of form input trial.id; 3411 tests pass
adapted bin/app.pl to take command-line args using getopts so port can be manually selected; added storage_racks.is_active col to syncona-14mg data feed
bugfix to M::History::_parse_patient_history_for_changes() - comparing original (NULL) & changed date vals caused uninitialized warning in DateTime module during auto-stringification, now vals are tested for existence (||= 'NULL') before comparison
changed HMRN::Data::hmrn() permissions to require edit_clinical_data as well as view_clinical_data, allowing simplification of HMRN permissions to edit_clinical_data OR view_clinical_data, not both
