Database management and OSM admin.

I did a little more with my database management.  I need to look at adding photos in to my models.  I was missing the __init__.py in my fixtures directory, but that still didn't help load in the data.  I changed some inconsistencies in my serializers and json_views.  I changed the admin and urls to make them OpenStreetMap Admin friendly.  I can now view streets in the geom part in the admin.
