Re: [webcomponents] Enumerate the element names which don't support createShadowRoot(), instead of looking at the binding property (#110)

That is interesting, because one of popular [Shadow DOM tutorials](http://www.html5rocks.com/en/tutorials/webcomponents/shadowdom/) use `createShadowRoot` on a now blacklisted element:

```
var host = document.querySelector('button');
var root = host.createShadowRoot();
root.textContent = 'こんにちは、影の世界!';
```
