allow return of dojo.Deferred (in addition to doh.Deferred) from test modules

[bill]

It would be convenient to return a dojo.Deferred from some async tests rather than a doh.Deferred. Actually, some of the tests are already doing that, like the editor tests:

{
	name: "wait for editors to load",
	timeout: 5000,
	runTest: function(){
	    return new dojo.DeferredList(
	        dijit.registry.filter(function(w){ return w.onLoadDeferred; }).map(function(w){ return w.onLoadDeferred; })
	    );
	}
}

Turns out that code isn't working.

Use duck-typing so that DOH isn't so picky about whether it gets a doh.Deferred or a dojo.Deferred (or some other object that supports the same API).
