updated tests to work with Test::WWW::Mech changes (eg text_contains works where has_tag_like fails)

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

completed functions to update patient details on a single request if patient has > 1 record - previously only possible on all requests attached to patient; modifications to quintiles gallium data feed

split gallium_data.pl functions into roche & quintiles scripts
