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 new functions in Utils; corrected syntax in debugging section of DB

new Paginator; added sha_digest to Utils

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

added time_now() to Utils

Local::DB outputs coloured query using Term::ANSIColor; new Local::QueryLibrary & Local::Utils
