Only create the JSONObject once when mapping photos instead of one time for each Photo. This takes memory usage from 75mb per mapped Photo to 22-25mb per mapped Photo.
Made the WebView object a private class global. Initially so I could access it outside of the method I created it and clear its cache, but since that isn't possible, I'll just leave it as a class global. It makes things a little easier.
Use the class global WebView instead of the method local WebView object in MapixInterface#initializeMap().
