Re: [fetch] XHR option to trigger busy indicators (#19)

In Gecko one can use a dummy iframe for this.  iframe.contentDocument.open(); starts the busy indicator, and iframe.contentDocument.close() would stop it. 
I assume other engines would have the same behavior if they followed the spec on document.open()/close() more closely.

But anyhow, I don't object adding API for busy indicator. Fetch spec of course wouldn't be the right place, but probably HTML.
