[FIXED][3.0] Item.js setText

[stever]

A menu does not have any method called doAutoSize. It's layout does. Any call to setText will fail. I guess no one calls it!

Original:

    setText : function(text){
        this.text = text||' ';
        if(this.rendered){
            this.textEl.update(this.text);
            this.parentMenu.doAutoSize();
        }
    } 

Proposed:

    setText : function(text){
        this.text = text||' ';
        if(this.rendered){
            this.textEl.update(this.text);
            this.parentMenu.layout.doAutoSize();
        }
    }

Fixed.
