Add status for background apps menu
Feature Summary
Geary shows a short message in GNOME's background apps menu, something like "Watching for new mail" so as not to confuse users.
How would you like it to work
Geary can use the Freedesktop background portal's SetStatus() method to set the status (at least I think that's how it works).
Relevant links, screenshots, etc.
NewsFlash uses background status to let the user know it is syncing RSS feeds automatically.
