Thanks for the PR. I've tried to avoid getting service-specific options in the configuration since this module isn't meant to be specific to YouTube (though admittedly that's the most likely use case). But if I recall correctly, we currently support the rel=0 or rel=1 option in the URL that the user types (or pastes). Meaning, they can add &rel=0 to it directly in their editor to support the option (as well as any other query string option). But if that's not working for some case let me know as that would be a good reason to add it to the module config screen.
