Finch 0.16.1

This is patch-release for Finch 0.16 that fixes a couple of io.finch.syntax problems:

• #896: deprecated syntax import (io.finch._)) conflits with exmplicit import (io.finch.syntax._)
• #895: import io.finch.syntax._ shadows scala namespace

We decided to un-deprecate the implicit syntax coming from io.finch._ as it's the only way to avoid breaking API change. So the previous style should work just fine:

import io.finch._
val foo = get("foo") { Ok("bar") }

To enable the Scala Futures support, simply add an import io.finch.syntax.scalaFutures._.
