- Reintroduced testDeleteStore - Added 'protocolsToIgnore' property to index recovery components - Added 'deleted' protocol to all ignorable store settings (ADM indexer, index recovery) - Return 'NodeRef.Status' for transaction changes queries (removes N+1 calls back to NodeService) git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@22290 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
