setting $Local:DB::NO_LOG_QUERIES true was preventing sql trace output in QueryLogger::log_query so moved it to QueryLogger to take effect on dispatcher log() command; new Utils::datetime_to_string method + test file
added hash() and array() to Local::DBIx::Simple::Result to return in list or scalar context - original only returned scalar ref, and to inflate dates in array()
replaced Log::Dispatch::File::Rolling with Log::Dispatch::File for deployment since LDF::Rolling creates redundant file and doesn't handle file permissions properly, and file rotation handled by cron anyway; added today() to Local::Utils
