Access iron request object

[flosse]

How can I get access to the iron request?

For example with the persistent crate, I'd do s.th. like this:

let mutex = request.get::<Write<Store>>().unwrap();

but client.request is not the irons request object.

@flosse I'm not sure that we should expose Iron here because Rustless possibly can work with another backend.

I see. So accessing iron extensions is generally not possible?

@flosse I'll try to make something with it.

The main problem is that we use backend::Request as a Trait, but Pluggable methods are not object-safe.

So we have two ways to fix this:

1. Expose Iron request as-is instead of our trait (with "iron" feature).
2. Expose get_iron_request() -> iron::Request method.

No, I think that will cause troubles :-\

Expose get_iron_request() -> iron::Request method.

That's better, because it's explicit but I'd call it just iron_request().
