Performance tweaks for AVM Indexing.

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.
