bug fixes: RecordComparator needs to also compare RDATA so the removeDuplicates step actually works reliably -- this was masked by the duplicate suppression in RRset; only allow one command line specified KSK, since commons-cli doesn't seem to handle multi-arg options correctly; do not croak on the lack of command-line keys for now;; Also: new dnsjava lib that contains NSEC3 changes for the -04pre draft
