Expose TextNode on Toolbar Button

[jszmajda]

I just created a patch to the editor source in order to expose the textNode that is the text of a text-only button in the toolbar. I needed this functionality in order to support a character counter plugin. I could see this sort of functionality being useful in other plugins as well that want to update toolbar button text.

Here's some sample code using the changed version: (charsCounterButton is defined as a global variable when created) charsCounterButton._UIButton.TextNode.nodeValue = 'Left: ' + this.LeftChars ;
