Title: add res.locals.use

This is a experimental implementation of feature request [issue 1120](https://github.com/visionmedia/express/issues/1120) which I opened.

I still don't quite understand connect/express ecosystem. As I see in [issure 1000](https://github.com/visionmedia/express/issues/1000) `app.local` is implemented by expando rather than prototype inheritance.

I don't know about javascript performance, but it seems to me that mixining to every response as I implemented is quite inefficient.
