removed some unnecessary namespace declarations
removed over-reliance on the buggy #delay method for delaying action on single associations; using a strategy where I save batches of 1 element, therefore applying the same strategy as in the collection batching.
changed on of the orm helpers methods to something more understandable
moved initializers somewhere else
made a small change: the worker already receives the class name as argument instead of the class. This way resque works outside of the box
implemented resque support
