Nosetests should now be able to run using the new configobj / app init setup

Lots of changes:
 - CELERY_CONFIG_FILE does not need to be set to the from_tests module
   to run tests anymore, in fact it *should not be set at all* and is
   specifically forbidden.
 - moved around the configuration to the new 2-file format
 - and generally adjusting the code appropriately.
