added more testing for specimens in new_request - still have issue with null entry in request_specimen table; new request validation forces specimen code to uppercase; gallium trial script tweaks; t/test-lib.pl switches off foreign_key_checks before re-building tables
dod displayed in outreach demographics section; patient_demographics.dod val updated if supplied from hmrn chronologies - pending; gallium scripts update
changed 'confirmation' flag in edit patient function to all_records; replaced FV_length_between & FV_max_length methodss in check_param_length validation - Data::FormValidator upgrade to v4.71 seems to have broken them
