ensure we stop all threads at exit

Leaving running threads at exit seems to lead to occasional bugs at
finalization on Ruby 2.0.0.  This could be a bug with sleepy_penguin
or kgio, too, so I'll have to investigate further.  For now, we'll
just destroy the IOs associated with each queue and let the threads
die on their own.

This changes the QueueEgg internals a bit and I've removed the unit
test for QueueEgg now since the rest of the server already works
well (and QueueEgg internals may change even more).

Queues/worker threads no longer have their own logger, it seems like
excessive configurability/complexity since acceptors do not have
their own logger, either.  This logger only exists to log bugs in
yahns, not the application, so using the server logger is sufficient.
