Schema has been updated, DAO written, garbage collection updated to clean out aspects. Also some seemingly unnecessary changes in visibility declarations to deal with strange intermittent Spring wiring failures in one of my tests. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/BRANCHES/WCM-DEV2/root@3560 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
