Add LiveBy amenities overlay/POIs on communities map

[badvision]

The current site uses LiveBy to present a custom amenities panel with several categories and sub-categories that can be toggled to overlay amenities on the communities map. This requires:

1. Adding a category selection panel overlay to the map (can look different from the current if needed)
2. Calling the REST API for Live-by to obtain the list of amenities for selected categories and adding these as markers to the map
3. Likely also you will want to change the Map constructor to disable google's default POI markers so the map isn't too cluttered.
