[ServiceWorker] How are unloaded tabs represented? (#626)

Mobile browsers put tabs into an "asleep" state to save memory & battery as needed. If you focus the tab later, the page is reloaded, but may regain some state within form elements.

This behaviour is completely unspecified, but I think we should put some guidance in the SW spec for these pages.

Specifically:

* Do asleep tabs prevent a SW moving from "waiting" to "active"?
* Do asleep tabs show up in `clients.getAll()`
