documentation for attributeChanged is wrong

[ojanvafai]

On http://www.polymer-project.org/polymer.html, it shows

attributeChanged: function(attrName, oldVal, newVal) {
//var newVal = this.getAttribute(attrName);
console.log(attrName, 'old: ' + oldVal, 'new:', newVal);
},

But, the only argument attributeChanged gets is oldVal.

I confirm that it only passes in the oldValue:

This needs to be an issue on docs https://github.com/Polymer/docs/issues.

In Canary, with native custom elements enabled, newVal is passed to attributeChanged().
In stable, the arg isn't passed.

Try: http://jsbin.com/uxumeq/2/edit

We should update the polyfills accordingly.
