Metacat

remove docid and rev from systemMetadata table

-remove system metadata guid -> local id mapping (there is no document for system metadata now)
-include system metadata elements when replicating data objects (TODO: transfer all system metadata structures with the docinfo request).
TODO: remove docid+rev from the systemMetadata table definition

add systemMetadataProvenance table for tracking those relationships

do not use XML files for storing SystemMetadata - use DB tables only.

Committing the change to the utilities tag to pick up fixes in newline handling at the end of the files. With this, the MetacatClientTests pass.

Commenting out these MetacatRestClient tests because the Metacat RestService is no longer registered as a servlet and needs to be removed, along with the associated MetacatRestClient and tests.

Fixed MetaCatServletTest test failures by removing the hardcoded username/passwords used in the tests and replacing those with data from metacat.properties.

Fix AuthLdapTest to use accounts that are more reliable when searching for existing accounts in the getPrincipals output.

Modified Metacat to build against the D1_SCHEMA_0_6_1 branch of the dataone schemas by incorporating the 0.6.1-SNAPSHOT version of d1_common and d1_libclient libraries, and refactoring Metacat code references to the d1 schema changed types.

In order to sync up with DataONE 0.6.1 changes, I'm backing out ObjectFormatService changes temporarily in Metacat. Most functionality will be rolled back in using the DataONE 0.6.2 tag, but some methods in ObjectFormatService (such as getListFromDisk()) will be moved into d1_libclient_java.
