TS-938 - Don't merge

Adding the config and a gen_server to handle the c* nodes. But this uses elysium 0.1.7 so the files changed are really misleading.

Also the query seems to work, but it is not currently being used.
Actually I'm not even sure the gen_server is registered on the ?MODULE name yet, I think the spawn has to return a pid before that can happen. I never liked {ok, State, 0} because if somehow there is already a message in queue there won't be any timeout, but it probably works (and is recommended in the OTP in Action book, although I have still have doubts). I have put this kind of thing in the start_link directly after gen_server returns the pid also.
