Toying around with tokio 0.1, futures 0.3-alpha, and async/wait.

src/main.rs implements a very basic HTTP fileserver, using tokio 0.1, futures 0.3-alpha, and async/await.

The 0.1 compatibility methods from (nightly) futures@0.3 are used to map the new futures from/to the old (stable) ones that tokio uses.

The code is commented extensively.
