Add bulk dispatch response handler registration.

This allows an entire set of handlers to be registered in one go,
which makes more sense when we're handling most if not all BAPS
responses.
Appease rubocop.
Add more response handlers.

At this point most of the BAPS responses found in playback are
understood by the dispatch.
Port the state dumper and components to EventMachine.

This is a very rough port and needs some cleanup, but it seems to
work now.  Will pass rubocop over it at some point.

Next up: getting it to feed into a model.
