External script support

[tomalec]

As for now all external <script src="files.js"> children of loaded content are removed, and not loaded/executed back again (as they have no .textContent).

But, when loaded dynamically (for example via <template>) they works fine.

Are they removed in purpose? Can't just remove and execute pragmatically script:not([src]) ones?

However, if we would like to do so, it would be nice to make sure both inline and external scripts are loaded/executed in correct order.

Now <script> and <style> tags are handled by <template> itself without any magic from x-html. For more sophisticated cases use PuppetJs/imported-template.
