viewer crash bug fix: fis the udp packets split of SendEstateList() large lists; Enforce size limits on the estate lists since currently required for viewers compatibily; improve handling of changes with large selected items. This is still bad, users may need to close and reopen the region/estate information to get correct Allowed and Banned lists after a change. This happens because of viewer resent/outOfOrder packets that completly break this lists updates protocol
