Re: [fetch] Aborting a fetch (#27)

I think this is the only way:
```
var request = new Request('http://example.com');
setTimeout(function() {
  request.abort();
}, 10000);
fetch(request)
  .then(statusHandler)
  .then(resposeAsHandler);
  .catch(abortCatchHandler)
```
And we can use catchable exception in thenable chain. This will prevent for calling `then` handlers and the exception can be catch in `Promise.prototype.catch`. But after catch the chain is restored and developer must know it. Also a don't know how to design in Promise pattern an exception, that throws in `request.abort` method in example above.
