Adding custom method to get the current user

[pokonski]

I explicitly didn't want to do this, since you can basically override current_policy in your Controllers and provide custom user instead of current_user. Much easier and less indirection.

Your way would be like this:

1. call to current_policy inside your controller
2. call to current_user inside AccessGranted
3. which again calls current_user in the controller.

By overriding the method you can go down to just one step

1. call to current_policy which uses current_user in the same scope.
