	- ALF-8806 RINF 41: Lucene Removal: Fix CopyService
     - ALF-9028: RINF 41: Fix Aspect cm:copiedFrom
   - ALF-9029 RINF 49: Lucene Removal: CheckOutCheckInService API
     - ALF-9032: RINF 49: fixes to cm:workingcopy aspect
   28996: Dev branch for De-Lucene work pending patches
   29004: Evaluator runs in read-only txn
   29006: Additional PermissionCheckedCollection.create method
          - Use an existing collection's permission check data (cut-off, etc) to wrap a new collection
   29007:
          CopyService and CheckOutCheckInService refactors to remove Lucene
          
          CopyService:
          
          Removed cm:source property from cm:copiedfrom aspect and replaced with a cm:original association.
          Added CQ-based APIs to query for copies
          Added APIs to support bi-directional walking of copy association
          Fixed sundry uses of cm:copiedfrom esp. all uses related to cm:workingcopy
          
          CheckOutCheckInService:
          
          Check-out now creates a source aspect cm:checkedOut with 1:1 relationship to cm:workingcopy via cm:workingcopylink
          Removed explicit use of cm:workingcopy aspect and replaced it with calls to COCI API
          
   29083: Audit tests fail when indexing is turned off.
          Also removed a getReader() call during rule evaluation, leading to a 'sub-action' read being recorded.
   29113: NodeDAO.getNodesWithAspects supports paging
   29135: Removed unused patch queries
   29139: Basic patch (still terminates with error) to upgrade cm:copiedfrom and cm:workingcopy
   29157: Tested patch for cm:copiedfrom and cm:workingcopy aspects
