[whatwg] Interface objects defined in Web Workers outside workers

[Simon Pieters]

It's not clear from the Web Workers spec which interface objects and  
constructors should be available to the non-worker context. Worker and  
SharedWorker obviously should be available, but what about AbstractWorker  
and the others? I think Worker, SharedWorker and ErrorEvent should  
probably be available, but the others not.
