Added the ability to continue without a token

[KieronWiltshire]

Here at Concept Gaming, we're implementing GraphQL. The setup makes things difficult to work with as GraphQL only exposes data through the use of a single route, this requires us to explicitly check specific end points. I'd greatly appreciate it if this could be merged rather than having us to re-implement it in our application.

@KieronWiltshire Have you confirmed your change is compliant with the OAuth 2 RFC? Please reference the sections of the RFC that apply to your change.

[KieronWiltshire]

@markstos it complies with the entire spec, it just allows you to catch the error and continue.

@KieronWiltshire It would be helpful if you linked to the specific spec section that addresses continuing without a token.

[KieronWiltshire]

@markstos the spec doesn't specify, to be completely honest, this isn't something I need anymore, well not as of right now, so feel free to close this merge request.
