DropDownSelect: cannot be created programmatically without a source node

[Bryan Forbes]

Every other widget in Dijit can be created by doing this:

var widget = new dijit.some.Widget({ /* properties here */ });

When you do that with dijit.form.DropDownSelect?, it throws an error:

node is undefined

It stems from the postCreate function doing this:

if(dojo.attr(this.srcNodeRef, "disabled")){
	this.attr("disabled", true);
}

To me, this seems unnecessary since the attributes of the node should be taken care of by _Widget if they are declared on the prototype (and "disabled" is declared on the prototype of dijit.form._FormWidget). I'm attaching a modified test which adds three DropDownSelects? to the test: two programmatic (of which, one is disabled), and one disabled from markup.

Assigning to Nathan although of course if you have a fix Bryan feel free to check in.

(In [19804]) Fixes #9655 - do not rely on srcNodeRef existing...it may not

(In [19808]) Refs #9655 - sometimes this.dropDown is missing as well - we need to account for that
