patched M::Outreach::do_letter_dispatch() to use insert_or_update_on_duplicate_key() instead of insert_or_update(); added array size display to outreach_notification_dispatch.tt
RDBO debug method changed again - now have to specifically ask for $RBDO::Debug to and $RDBO::Manager::Debug using DDBO_DEBUG & RDBO_DEBUG_ON env flags - difficult to get desired outcome from fastcgi processes, crons, devel server and test scripts wrt log files and stderr
changed RDBO_DEBUG flag to RDBO_DEBUG_ON; view_lantronix_log function - unfinished; hilis4.fcgi checks for CENTRE env var and checks pidfile before creating new
changed LIMS::RDBO Rose debugging flags to require RDBO_DEBUG env param to be set - eg lims_server.pl, locally in test scripts, or export console ENV param
replaced multiple calls to load config settings with LIMS:Local::Config->instance(), using Class::Singleton to ensure config file opened & read only once at server startup
