Allow configuration of Cookies.

Allow the `Lotus#configuration` to inject the `Lotus::Action::Cookies`
module in your application’s controller.

When the application is loading the framework,
`Lotus::Loader.load_frameworks!` will inject the before mentioned
module if the configuration is set.

Closes #1.
