This will need work to do a temporary Redis server that vilebot will read/write to in order to do proper junit testing.

We should get this started before accepting more fixes and 'features'

I've started work on integration tests for some of the less trivial features (e.g. database interactions) starting a redis instance, testing that interactions work as expected, then stopping the instance and cleaning up. Once thats done I'll start looking into ways of testing the handlers.
