NodeInfo tree working (besides litho nodes)

Summary: The second tree has access to all AX NodeInfo properties (they are not in the sidebar yet). Infrastructure set up to customize displayed information bassed on what is most useful. Descriptors for views updated to include AX functionality and non-view descriptors AX functions defaulted to null/empty. Non-view nodes (like Fragments, Window, Appication) no longer included in AX tree. Corresponding nodes will be highlighted (although not expanded) on click in either tree.
