Return the Lat/Lng coords of the photosphere as you move though the map

[MichaelTaylor3D]

This PR makes the onSuccess callback possible on android, and it returns the lat and lng in the callback for the photosphere every time you move.

    <View style={styles.container}>
      <StreetView
        style={styles.streetView}
        allGesturesEnabled={true}
        coordinate={{
          latitude: 39.151607, 
          longitude: -76.859979,
        }}
        pov={{
          tilt: parseFloat(0),
          bearing: parseFloat(0),
          zoom: parseInt(1),
        }}
        onSuccess={(data) => console.log(data.nativeEvent)}
      />
    </View>

I wasnt sure why its looking for links but it was preventing the link from firing when otherwise a change was made. I can add an extra if statement if there is something special we want to handle for this case.

It seemed to me the reason the onSuccess Callback wasnt working is because the event names were mismatched. So with this change I made it all the same as whats in the NSTStreetViewEvent.
