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
patched M::HMRN::update_comment() to look for form content befroe inserting new record, to prevent insert of empty comment field; reduced number of fastcgi process to 3 in preparation for new centre; reduced number of tables in create_core_data.gz
increased fastcgi processes to 4; bugfixes - outreach weight only converts imperial pounds if exists & list all screen tests skips inactive screen terms
