Removed calls to getXXXPaths(). Changed mappings of properties and aspects on AVM Nodes to favor get all calls. Added getAspects() and getNodeProperties() which take AVMNodeDescriptors. Used these in AVM Indexing to reduce the number of redundant full lookups. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@6121 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
