Stuck Thought Event Creation

Processor to receive StuckThoughtEvent from Interceptor and to decide what to do with it before it gets emitted. Should be able to enhance/subdue the event emitted by the interceptor.

Should identify what the end of the chain of thought is, rather than flagging against some arbitrary event.

Could possibly create TriedAttemptsEvent, or even store in StuckThoughtEvent, or could leave that to a subsequent processor.
