skip trial reportts from print run; merge Model::PrintRun _print_run_excluded() and get_print_run_request_ids() to get single query, but RDBO cannot handle complexity so need to replace with SQL::Abstract::More method as used by print_run.pl
MAJOR CHANGE: moved sql_lib() from M::Base to new M::Role::Query; moved all M::R::QueryFormatter methods into M::R::Query; removed sql_lib() from ScriptHelpers - using new M::Roles::Query method; removed lims_dbix() from M::Base - now loaded via M::Role::DBIxSimple on demand; moved get_sql_with_constraint() from M::R::DBIxSimple to M::R::Query; method gets dbh from lims_db not lims_dbix in M::LabSection::update_lab_sections() & M::Specimen::update_specimens(); added elements() to Local::QueryLibrary
fixed M::Request::get_new_and_relapsed_cases() to correctly handle org_code as scalar or arrayref; simplified print-run section to retrieve request ids from excluded locations; refactored & speeded up some slow audit queries
