- pass parent_id to instance_select_query (still fallback on folder_id, if not set) - if parent_id for instance_select_query is empty, don't constrain on folder_id or parent_id
- ::xo::db::Class->get_instances_from_db: return order-composite with object of the actual type (not only ::xotcl::Object) - provide option '-quoted" to update_revision to allow sql-functions to be passed as well - flush cache entries in CrItem->set_live_revision
