Refactor config. framework feature definition

In spite of using the sign_in_token option as an example option,
this feature definition does not test if the Devise `sign_in` method
gets the correct arguments, but only tests that the configuration
framework allows to store settings as expected.

As they were written, the scenarii were a little missleading.
In fact, I was wrong when stating that c983d17 did fix the issue #19.
Add (already passing) sign_in_token option scenarii

Add FactoryGirl support to dummy app (was uncomplete)

Note: The addition to ActsAsTokenAuthenticationHandlerMethods is
questionnable.

I believe there should be a more elegant way to ensure that
the required Devise methods are available in test environment,
moreover I'm not really sure why they weren't already available :/.

I hope the way I included Devise::Controllers::SignInOut will make
this issue more visible :)
Refactor improve the sign_in_token option feature readability

Note: this commit is the one which really fixes the issue #19.
