WaterSmart-404

"Share this page" fix to properly restore the county map.
Aha! Good call. I bet that the geogjsonformatter can detect the geom cycles that a generic serializer wouldn't be able to contend with. Since the cycles problem is solved, this can probably be merged if you are in a pinch. If you have time, it would be swell to move the countyFeature and waterBudgetHucFeature to StoredState.
