SVG Sprite in JavaScript
**Is your feature request about the Usage? Please describe.**

If the website and SVG sprite are hosted in different servers (many big sites use dedicated server for static files), browser will prevent cross site reference:

```html
<!-- http://en.opensuse.org/ -->
<svg class="remix">
  <use xlink:href="http://static.opensuse.org/svg/sprite.svg#stack-line"></use>
</svg>
```

**Describe the solution you'd like**

The solution is very easy. Provide JavaScript `sprite.js`:

```js
(function(){
  var container = document.create('div');
  container.style.display = 'none';
  container.innerHTML = '<put svg sprite content here>';
  document.append('container');
})();
```
