Updating celery_setup.from_celery to use new config loading / app init

- The code for this is significantly simpler now.  The app sets up
   everything but celery, and from_celery finishes the job.
 - There's no more specifying the mediagoblin section in the file,
   which doesn't make sense anymore and was already confusing.
