919981 - Dispatch app (un)install events via the webapps actor

Status: VERIFIED FIXED

(DevTools Graveyard :: WebIDE, defect, P1)

Description

[Alexandre Poirot [:ochameau]]

So far, we can listen for app being opened/closed, and we can list installed apps, but it would also be usefull to receive events when an app is installed or uninstalled. That would help managing the list of installed apps in the device panel.

It's a bit sad to add new observer notifications, but we'll fix that later.

Since you only need the manifest url in webapps.js, don't use cloneAppObject which is expensive, but just create an object with the manifest url.

nit: is that < 80 chars?

Any reason to send an app JSON object? If we only need the manifestURL, why not just send it?
