Port to scalaz-stream in progress.
Rudimentary servlet example working again.
Prune dead code.
Remove useless process.
Resurrect some Writables.
flatMap(identity) is join. Thanks, @stew.
Writable functors
Better writable functor.
In fact, traversableWritable can go away now.
Eliminate Akka dependency for ByteString.
Bring back text body parser.
SIP-18, schmip-18. Import cleanup, too.
Support scala.concurrent.Future and scalaz.concurrent.Task in servlet backend.
Synchronous servlet backend via IO monad.
Replace half-baked IO with half-baked Trampoline.
Broken netty

Callback never happens, service(request) fails for some reason. Probably
made a bad Process.
Task still doesn't eval

Pattern matching doesn't seem to be working for me anymore either. Might
be a failure on my part.
Use local queue to create request body.
Remove Bytes because scalaz-stream did.
Merge branch 'topic/scalaz-stream' into topic/scalaz-stream-broken_netty
