do not use pisco for referral testing (merge from 1.9.5)

merge 1.9.5 changes to trunk (delete now preserves access rules and docs can be read after deletion)

CNCoreImpl is replaced by CNodeService

Get username and password from a property file.

Updated tests to use ObjectFormatCache.getInstance(), and added tests for CNCoreImpl.listFormats and getFormat().

When calling SystemMetadata.getObjectFormat(), return the string value of the ObjectFormatIdentifier rather than ObjectFormat.toString() (which no longer returns the fmtid string).

organize imports so that it is clearer what dependencies exist on the D1 jars

Merged in the D1_0_6_2_BRANCH changes that include the transition from ObjectFormat calls to ObjectFormatCache calls.

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

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
