fix for 'mysql server has gone away' message - new DB check_db_connection() method clears dbix object if no ping received from db, forcing dbix object recreation; wrapped 'horrible' deferred keyword in flash() method; dev logger uses Console::Colored output
bugfixes - switched deployment to YAML file sessions as DBIx not working - maybe cookie handling issue; removed line-break in textarea markup causing 'required' flag to fail
