Changes for graph analytics:
- Added missing support for global tile/bin analytics to GraphAnalyticsBinner app
(and re-added to/from String calls to AnalyticsGraphRecord ... which was needed for the above to work properly)
- Changes to client side rendering of graph community nodes and labels including thresholds for which communities/labels to render and font sizing.

Fix analytics for graph tiling.  Where other hierarchy levels are showing number of children, show something useful on hierarchy level 0 (where, by definition, there are no children). [Note that hierarchy level 0 != tile level 0, the orders are opposite.]
