Event-based STOMP header generation (#839)

* More flexible headers for STOMP messages, theoretically.

* Lower the priority of the base implementation.

* More context.

* Add in the "aud" claim.

... ensure we're dealing with our tokens.

* Rectify the other base class.

* Remove some chaff intro'd from merge conflicts.

* Return after failing to find the "aud" claim.

* Permissively allow without the "aud" claim...

... _could_ roll more conditionally, with some state set during an update
hook; however, seems like unnecessary complexity.

* Couple of coding standards things.

* Add the use of the class back in.
