TabContainer - Calling setLabel on controlButton of tab fails

[guest]

Trying to set the tab's label from code fails due to the fact that containerNode is not defined for a dijit.layout._TabButton.

Adding the following code to test_TabContainer.html shows the error

dojo.addOnLoad(function(){
	...
	document.body.appendChild(p);
	dijit.byId("tab1").controlButton.setLabel("Updated Title");
});

The controlButton is a dijit.form.Button in the end and the setLabel function uses this.containerNode. So the quick answer is to add that as an additional dojoAttachPoint in the template string for the dijit.layout._TabButton.

Patch attached.

(In [9997]) Fix setLabel() on a tab button (although eventually we should have a way to change the title of the actual pane and have the info reflected to all controllers maybe? Not sure. Changing label directly is not officially supported.) Fixes #4031.

PS: note that the above technique is not recommended... changing the label will make the tab shorter or longer which (in exceptional cases) could change the tabs from taking up one row to two rows, or vice-versa, but the TabContainer? won't know to reformat itself.
