title: GeoDjango PointField admin visualization
body: <p>I was wondering how I could change the default PointField visualization (the Openstreetmap) in admin so that I could enter simple latitude/longitude instead of select a point on the map?</p>
  
  <p>I looked at this one <a href="https://stackoverflow.com/questions/17021852/latitude-longitude-widget-for-pointfield">Latitude/longitude widget for pointfield?</a> but could not get it working in any way in Django 1.6b4</p>
  
  <p>Thanks</p>
