function to retrieve previous requests combined with get_single_request_data() so available to all views (search, results, report, etc); extended outstanding lab-tests display to unreported & unauthorised worklists
added patient summary header to all request-related pages (phonelog, errorlog, email, data edits, unlock record, etc); option to switch off gross description field
standardised all Model classes using Moose to read 'extends' then 'with'; moved M::R::ReportUpdate::_do_additional_tests to M::R::LabTest::Update::auto_request_additional_tests() for sharing with M::R::ResultsUpdate::do_results_summary_update() so result summary input can auto-request new lab tests - required reconfiguration of additional_tests.yml; changed order of result summary drop-down and textbox entries when joined to form single string
consolidated separate get_ontstanding_tests logic into single method call from get_single_request_data(); guest users see 'has lab tests pending' on summary page
moved _get_outstanding_tests() from C::Report to C::R::RecordHandler for sharing with printing and displaying report; moved all additional comments, errors, etc to common section at foot of body of printed report
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
