Got mapbox working :) , Introduced option to swap between map and listings view (see description for pending)

Pending: Using lat longs of the retrieved search results to populate
feature objetcs in geoJSON. I don't know how to get this data in
listings index (they seem to be in different pages - should I pass the
results to this page or is it already available?)
