* Handle -> Remote * Pinned -> Handle All APIs now take a `&Handle` by default and in general can return an immediate `io::Result` instead of an `IoFuture`. This reflects how most usage will likely be done through handles rather than remotes, and also all previous functionality can be recovered with a `oneshot` plus `Remote::spawn`. Closes #15
