excluded exempt nhs number categories from M::Audit::nhs_number_supplied(); changed M::R::DBIxSimple::constraint (Str) to ::constraints(Array) to handle multiple constraints; included a skip list in mail_reports.pl; placed constraints list in forms in toggleviw container
moved M::Chart::get_sql_with_constraint() and _get_search_constraints() to M::Roles::DBIxSimple for code shart between M::Chart and M::Audit; replaced C::Chart::_get_chart_title() function with __PACKAGE__constraint_title, set in M::Roles::DBIxSimple::_set_chart_constraints()
