GeoNode fixtures

[Ben Wyss]

Back in the day some code was committed to the GeoNode api relating to fixtures (https://github.com/gem/FaultedEarth-Django/commit/31ba35085e536b6a8a0758e7df1e6565a6693e98 ). There was no documentation added for fixtures. Now we need to go back and see:
    a) what was done regarding fixtures,
    b) understand if more work needs to be done to make fixtures usable,
    c) understand how to use fixtures to maintain the database data when a database rebuild is preformed.
    d) document document document

currently a lot of the GeoNode documentation (GEM customizations/configuration) is done in blog form at openquake.org. perhaps we should re-think this approach? Maybe it should be added to the GeoNode api README?

The fixtures file was out of sync with the database schema. Once the fixtures file was updated (and placed in the appropriate path) they were loaded correctly.

One can also manually load data with fixtures with:

python ./manage.py loaddata /var/lib/geonode/src/GeoNodePy/geonode/observations/migrations/fe_fixtures.json

I added a wiki about how to add fixtures: https://github.com/gem/oq-ui-api/wiki/Add-fixtures-for-a-Django-application/_edit
