Checking instance type should allow subclasses.

On the dojox.mobile.common.js, checking if a widget is a instance of dojox.mobile.Heading is too strict. I can't make subclass of Heading because of this. Also I think that all the function of dojo.addOnload should be overridable.

line 368: dir = (w instanceof dm.Heading) ? -1 : 1;

This should be like: dir = w.isInstanceOf(dm.Heading) ? -1 : 1;

The instanceOf check should return true for subclasses of Heading as well. How did you create your subclass? I guess it is not recognized as a subclass of Heading.

You were right. I didn't notice about that the instanceof keyword accepts subclasses. Maybe I just mistook something. Thank for your reply.
