added skipped_lab_tests & added_lab_tests arrays to M::Roles::ScreenUpdate::do_new_lab_tests to return outcome info to Controllers; replaced 3 object attributes with 2 LIMS::DB queries in M::Roles::ScreenUpdate::_have_required_sample_type_for_lab_test(); ErrorHandler uses L::Model::Email instead of L::Local::Mail - supplies required _app_cfg - email-admin function now works
patched C::Screen::edit() to use same screening function as used at initial screen; fixed a lot of failing tests due to new screening functions - report_status.t still failing
moved request audit in screening function to optional & disabled it; moved set_querylog_args & set_errorhandler_args near top of cgiapp_prerun() so they take effect for login & session update handling
added allow_inline_column_values() to DB::User to allow 'NOW()' to be passed inline - first attempt to fix peristent "could not parse datetime 'now' - invalid date format" error
new screen_category table; moved screens 'type' col to category_id; modified all screening terms & screening tests admin functions to accomodate new screen_category table; removed ajax validation from screen description & lab test field_label as these use 2 & 3-col unique keys so can't be validated by AJAX; email reports function uses users secure email address as sender; modifed portal_access function to supply SHA1 hash of current date - so failed login not sent back to portal page without explanation; modified mail_reports.pl to use item names instead of table id accessors
