1: 500px now fetches images based on location and range perfectly (!)
(no more porn!)

2: Images now show whenever gps gets coordinates (triggered by
"onLocationChanged" instead of being asked by a timer in the app)

3: Everytime a new image search is done, the list is renewed to avoid
photos that are not related to the search to appear

4: App is handling memory way better now because of 3.

5: Images load much faster now because of 2.
