Finch 0.3.0

This is another big step for Finch. An enormous work has been done by core contributors: @benjumanji, @rodrigopr and @rpless. Thank you guys!

The following changes are made:

• Finch is on Scala 2.11.4!
• Finch is now on finagle-httpx (Netty-free implementation of HTTP), which means that new client/server construction API may be used instead of deprecated ServerBuilder:

Await.ready(Httpx.serve(new InetSocketAddress(8080), endpoint.toService))

• An Endpoint companion object has an apply method that builds new endpoints on the fly:

val e = Endpoint[String, String] {
  case Method.Get -> Root / "a" => ???
  case Method.Get -> Root / "b" => ???
}

• Futures may be used instead of services in the Endpoint route's destination:

val e = Endpoint[String, String] {
  case Method.Get -> Root / "a" -> "a".toFuture
  case Method.Get -> Root / "b" -> stringService
}

• Finch supports the Argonaut library that provides purely functional JSON API.
• The code coverage has been dramatically improved.
