Title: Drop `require` check&override in spine/relation module

I've loaded *spine/relation* module using `require 'spine/relation'`, but looks like "kanso's" `require` support was overridden here @cf5e8b89. I'm not sure how this module should be loaded, but looks like `required` function will always be available inside kanso package.

Please review my changes and if everything is OK, please push it to kan.so repo.

Thanks,
Yury
