added _centre to %settings in lims_config.pl as $ENV{CENTRE} not available to app so Admin::Config::Settings::_get_settings could not load correct file for Oxford, Cambridge, etc; added base_href setting for wkhtmltopdf use in templates
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
moved config settings to own directory in /config dir - settings file depends on CENTRE env param supplied by init.d script; C::DataImport::do_bcr_abl() method now does auto-report after setting required lab-test status to complete - request_history depends on auto-report function succeeding; minor change to auto_report.t to match current auto-report rules for CML; Outreach charts set USE_FILE_SESSIONS param to force non-db sessions; Outreach MGUS cases with IgM paraprotein by electropheresis loads B-LPD questionnaire instead of MGUS one
