added callback to C::WorkList::display() to display requesting username of requested test/panel; removed MooseX::AttributeHelpers from all classes - using Moose::Meta::Attribute::Native syntax
minor re-arrangement in M::Result::get_section_lab_test_results(); switched new_referral_source and new_referrers scripts JUST_TESTING flag on and switched new_national_code JUST_TESTING off
fixed ErrorHandler to work with dev server - needed content returning not printing so CGI::App handled it properly; moved html content to errorhandler.tt template
patched sprintf error in C::Worklist::display(); added default {CENTRE} to C::Admin::Config::Settings::_get_settings so correct config file loaded using existing init.d/lims-fastcgi
