Commit Message

Add `thunk` middleware.

Sometimes you want to change the processing mechanism of your application at runtime instead of construction time. For example:

```javascript
const app = compose(
  match(path('/foo'), send())
);
```

This app structure is static; what if we wanted routes from a database? Such a thing is now possible in relatively elegant fashion:

```javascript
const app = compose(
  thunk((app) => {
    let result = app;
    db.on('update', (routes) => {
      result = routes.reduce((result, route) => {
        return middlewareForRoute(route)(result);
      }, app);
    });
    return () => result;
  })
);
```

The `thunk` middleware basically defers access to the appropriate method (e.g. `request`, `error`, etc.) to the last possible moment at which point it calls the thunk to get the method at that instant.
