Metacat

check system metadata for the id as well (in cases when we only have system metadata)

include GUID column for xml_access and related methods for storing/retrieving access rules

implement the old interface for now (until 0.6.2)

include CNCore implementation - only registerSystemMetadata is implemented at the moment. also - updated d1 jar (0.6.2) should be used since that is where the method is defined.
would like to consider making ResourceHandler more modular - seems like it does A LOT of different things

include System Metadata forced replication - just need to figure out when to call it!

handle timed replication of system metadata. there are still a few outstanding issues:
-track server location of system metadata-only entries
-replication policy flag for system metadata-only entries?
-locking for replicated entries?
-forced replication of entries

read and write D1 access policy rules from metacat xml_access table.
still TBD: which mechanism takes precedence when there are systemMetadata access rules and EML access rules and other access rules?

persist system metadata replication policy and status using db tables

rework SystemMetadata creation when inserting documents via the Metacat servlet api (in which case there was no client-supplued system metadata)

do not look in systemMetadata for a docid->guid mapping
