* Added 'RDSchedRulesModel'. * Added a pseudo-schema change to force checking of schedule code rules. * Incremented the database version to 348. * Added a check for scheduler code rules to rddbmgr(8). * Refactored the 'Scheduler Rules' dialog in rdlogmanager(1) to use the model based API. Signed-off-by: Fred Gleason <fredg@paravelsystems.com>
