Replace Mapzen with Google Maps

[pral2a]

Mapzen is being deprecated so we'll need to move to the Google Maps API:

Lines 42 to 99 in e1c3831

	function querySearch(query) {
	return $q.all([getMetadata(query), getPlacesMapzen(query)])
	.then(function(data) {
	if(data.length === 0) {
	//enable scrolling on body if there is no dropdown
	angular.element(document.body).css('overflow', 'auto');
	return data;
	}
	//disable scrolling on body if dropdown is present
	angular.element(document.body).css('overflow', 'hidden');
	return joinSearches(data);
	});
	}
	function getMetadata(keywords){
	keywords = keywords.replace(' ', '+');
	return asset.getMetadata(keywords);
	}
	function getPlacesMapzen(location){
	location = location.replace(' ', '+');
	return $http.get('https://search.mapzen.com/v1/autocomplete?api_key=search-h8Qe8fY&text='+ location);
	}
	function filterPlaces(places){
	if (!places || !places.data || places.data.features.length === 0){ return [];}
	places = places.data.features.slice(0, 3); //just first 5 results
	return _.map(places, getMapzenPlaceReadyForModel);
	}
	function filterEntities(assets){
	if (!assets || assets.length === 0){ return [];}
	return _.map(assets, getMetadataReadyForModel);
	}
	function getMapzenPlaceReadyForModel(place){
	var searchResult = {
	type: 'location',
	name: place.properties.label,
	longitude: place.geometry.coordinates[0],
	latitude: place.geometry.coordinates[1]
	};
	return new SearchResultLocation(searchResult);
	}
	function getMetadataReadyForModel(asset){
	return new SearchResult(asset);
	}
	function joinSearches(data){
	var e = filterEntities(data[0]);
	var p = filterPlaces(data[1]);
	return p.concat(e);
	}

URL to the API works fine standalone:
https://maps.googleapis.com/maps/api/place/autocomplete/json?key=AIzaSyCMUbKxhE3BWLRClSC6lxcWHMgXr7BB-J4&input=pujades

But we are getting the CORS error

Maybe we need to load a Google Places library, and use their built in functions?
