updated TODO, moved some code from the worker in to utils.py, added a new 'job done' so that the worker doesn't tell the broker what jobs it has done as part of the get job message, added a count argument to the get job message so the worker can request a bunch of jobs at once, added batched postgres inserts which vastly speeds up the insertion process, generally refactored some code.
