Support JWT Auth

I just reviewed and tested this patch on my projects. I tested on the latest release 2.0.4. Works as expected.
Patch is trivial. Would be nice if it gets in, in the next release.

What module is providing jwt_auth? I wish they'd alter the routes to support this method, since it isn't scalable to add arbitrary methods.

Okay it's from jwt. I suppose there aren't going to be that many other auth providers for decoupled applications.

Committed, thanks!
