config.py assert on config.private.json keys

[luke-john]

There is currently an assert on config.py https://github.com/timvideos/streaming-system/blob/master/config.py#L64 which is throwing the Makefile when you try and serve.

Given that config.json is intended to hold default/testing values and not real data, I think removing this assert makes sense.

Yes, makes sense.

BTW Would you mind moving all the pycon stuff into a config.private.json.example ?

Sure, I've added a separate pull request #50 with this file added.
