- removed deprecated egw_db->Halt_On_Error handling in favor of just exceptions - added a couple of exceptions extending egw_exception_db to be able to detect different problem areas - fixed setup to use / catch exceptions - new egw_exception_db_setup displays link to setup below exception message, to cope with no longer allowed html in exception messages
