dojo/Stateful: add a setOptions({}) function

[raupp]

there are some reason for the "Stateful" don't implement a "SetOptions?" function like that:

setOptions: function(options){
                if(dojo.isObject(options)){
                    for(opt in options){
                        this.set(opt, options[opt])
                    }
                }
            }

This function will help when data come server, for example, and need to be reflected on widget that uses one stateful as base.

dijit/_WidgetBase does this via set() but for some reason Kris didn't copy that functionality when he made dojo/Stateful.

Stateful has supported foo.set(options); for more than 3 years (​https://github.com/dojo/dojo/blob/418a356902586a2644e7d9d6920587101b83187c/Stateful.js#L51-L56) but is this a request for something else?

My bad! I really didn't see this in dojo/Stateful. Please ignore this ticket. I promise I will be more careful next time.
