Include properties in BiG CZ GeoJSON results

[kdeloach]

Instead of returning a list of results which contain GeoJSON fields, we may to return a GeoJSON collection with properties. This would simplify interactions between the sidebar and map on the frontend by reducing the amount of data transformations needed.

For example, instead of:

{
   "catalog":"cinergi",
   "count":1,
   "results":[
      {
         "id":"edc761d4fe734000ba0ba228867ae9cc",
         "title":"Tropospheric Emission Spectrometer (TES) Data and Information",
         "description":"...",
         "links":[...],
         "created_at":"2017-03-17T17:14:29.817000Z",
         "updated_at":"2017-01-13T23:01:16Z",
         "geom":{
            "type":"Polygon",
            "coordinates":[...]
         }
      }
   ]
}

we could to:

{
   "catalog":"cinergi",
   "count":1,
   "results":[
      {
         "type":"Polygon",
         "coordinates":[...],
         "properties": {
            "id":"edc761d4fe734000ba0ba228867ae9cc",
            "title":"Tropospheric Emission Spectrometer (TES) Data and Information",
            "description":"...",
            "links":[...],
            "created_at":"2017-03-17T17:14:29.817000Z",
            "updated_at":"2017-01-13T23:01:16Z"
         }
      }
   ]
}

We just need to think about how to handle results with unavailable geometries (ex. HydroShare). Something else to consider is replacing the top-level result object with a FeatureCollection. This could work as long as we're able to attach properties for next/prev page URL, number of results, etc.
