Follows w3c/ServiceWorker#1199.

See whatwg/whatwg.org#197 and whatwg/meta#92 for details.

This also updates the web-platform-tests and IRC URLs.

This gives a more consistent story for event dispatching. The former setup was especially buggy if native replacement is not supported.

This also reduces duplication (such as waiting for fetches).

And it queues a task for the show and close events.

There are no implementations for this property, and the native
notification centers of various platforms make it hard to support this
properly.

  - Windows Action Center toasts have an <audio> element supports
    built-in sounds, as well as sounds included in an application's
    package, but not freeform path and/or URL support.
  - NSUserNotification (Mac OS and iOS) have a `soundName` property that
    will be resolved against files in various local system directories.
  - Android strongly prefers usage of the RingtoneManager for sounds.

Even though it could be supported on certain platforms, it's currently
underspecified: which codecs should be supported and what is the maximum
duration of the sound (if any), making it very unpredictable at best.

We can revisit supporting sounds if there is interest from
implementations.

Remove "substeps" and define "list of notifications" as a list and manipulate it as such.

This reverts f2e3cad and 53ebcf2.

It also ensures notificationclose is dispatched when replacing a notification.

(There are many inaccuracies remaining regarding tasks that need to be fixed in a follow-up.)

Fixes #90.

Also adjust indentation a little here and there.

Also resolve all outstanding Bikeshed warnings. Closes #88.

Using entry global object (equal to entry settings object’s global
object) is not needed here and we generally try to phase out entry.

They are not implemented and there’s no interest per Peter Beverloo. We
can reinstate these if that changes.

Also clarifies meaning of existing icon and badge properties. Fixes #79.

Fixes #66.
