All instances of `old_io` and `old_path` were switched to use the new shiny `std::io`, `std::net`, and `std::path` modules. This means that `Request` and `Response` implement `Read` and `Write` now. Because of the changes to `TcpListener`, this also takes the opportunity to correct the method usage of `Server`. As with other languages/frameworks, the server is first created with a handler, and then a host/port is passed to a `listen` method. This reverses what `Server` used to do. Closes #347 BREAKING CHANGE: Check the docs. Everything was touched.
