Kallithea wrapper of Celery

The Celery configuration is in the Kallithea ini file but must be converted to an

entirely different format before Celery can use it.

We read the configuration from tg.config at module import time. This module can

thus not be imported in global scope but must be imported on demand in function

scope after tg.config has been initialized.

To make sure that the config really has been initialized, we check one of the

mandatory settings.
