Support custom buttons in modal-footer?

[Andreas-Hjortland]

Would it be possible to add support for custom buttons in the <modal-footer> element? As of now you only support <button> and <au-button> which doesn't allow custom elements.

In my case I use a custom element <ladda> which gives the submit button a spinner when you click it.

@Andreas-Hjortland Yes this is fine we can certainly switch to a more open content selector, PR accepted.
