Mac App Store: Don't show updates for an uninstalled app
Nathan - I made a mistake on a mac where I wasn't the main administrator.   I sure meant to delete the app and even dragged it into the trash, but a day later when the update bubble was still there, I found I didn't really delete the app (In my case it was installed on a different user on a multi user system and rather than move to the trash, it copied itself to the trash). Once I really moved the app to the trash with an admin user and rebooted, the update badge disappeared.
