* Added a 'STACK_SCHED_CODES' table to the database. * Dropped the 'STACK_LINES.SCHED_CODES' field from the database. * Incremented the database version to 308. * Renamed the 'SchedCartList' class to 'RDSchedCartList' and refactored it to be idiomatic Qt. * Renamed the 'SchedRulesList' class to 'RDSchedRulesList'.
