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 L:Dispatch to avoid error on undefined dispatch_path; moved L::Local::QueryLog dispatcher construction from _warn_handler() to BEGIN block to avoid re-creation per request; changed sql.log to Log::Dispatch::File::Rolling object; amended log_rotate.pl to process the new sql.log filenames; added new method ensure_warn_handler_capture() to L::Local::QueryLog for use with non-external fastcgi, where FCGI re-defines the warn handler set in L::L::Q so that sql statements go to Apache error log
