Button: Error on IE6 calling setLabel("") if showLabel=false

[guest]

Try the following code on IE6:

var b;
b = new dijit.form.Button();
b.showLabel = false;
b.setLabel("");

you'll get:

[ Error: 'undefined' is null or not an object ]

Same problem this way:

<button dojoType="dijit.form.Button" showLabel="false"></button>

Attached patch fix the problem.

Proposed patch to fix problem

(In [12015]) Fixes #5573. Added blank default for IE6 and moved _layoutHack to _formWidget so that Button could pick it up.
