added new function to require confirmation when reporting with outstanding test results; moved C::Report::_get_requested_tests() to C::Roles::ResultHandler; converted some template data objects to as_tree hashrefs to prevent db lookups when empty; fixed some tests to comply with new confirm_outstanding_results flag
MAJOR CHANGES: search form uses jQuery watermark instead of dd-mm-yyyy display - changed date-field validation to accommodate; moved do_new_lab_test() method out of M::Role::ScreenUpdate to new M::Role::LabTestUpdate to share function with auto-requesting tests at diagnosis/authorissation; changed 'teaching' field to radio button in report page and changed handling of report_option fields in M::Roles::ReportUpdate::do_additional_options() - all request_options were being cleared during report stage; added updated_at timestamp field in M::Roles::ReportUpdate::do_request_report() to any unchanged request_report object to trigger mail_report.pl on authorised cases - were being missed as updated_at col was not being modified
screening functions (new & edit; not yet auto-screen at new request) display outcome summary of which lab-tests requested & which (if any) skipped; fixed many *.t issues caused by adding patient notes form to report page - made 'report' a multi-form page
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
