Title: ActionController::Live documentation in the guides.

`ActionController::Live` is in my opinion a very important feature of Rails, but most of the documentation is on @tenderlove's blog. I'm adding documentation to the `action_controller_overview.md` guide which should tell people how to stream arbitrary data.

I'd love comments!
