Registering an error handler on the root zone

[owenkrafft]

I want to collect uncaught exceptions throughout my code in an error handler to use for reporting purposes, but exceptions in Promises don't fire window.onerror. An error handler on the root Zone seems to work quite well, but it seems that the only non-ugly way to register an error handler is during Zone construction by passing in a ZoneSpec with an onHandleError function, and the root Zone is constructed automatically.

Is there a recommended way to do this or another approach I can use?
