Change new updates notification icon

[haarp]

Hello,

similar to kitsunyan/foxy-droid#74, I'd like to request a change of the new updates notification icon.

Currently it is an exclamation mark, indicating that the notification is very important needing immediate attention. this seems to be because the icon is "new_releases" in the "Av" category, which seems to be media/Youtube-related. It may make sense to use this icon within a media app, but it doesn't suit a package manager well.

How about "update"?

Thanks a lot!
