Move any visible account settings into AccountSettings. (#6308)

* Remove the now unused setting to disable in-app notifications.

* Move visible account settings into AccountSettings.

Have ignored enableNotifications for now as that will require reworking the NotificationManager.

* Allow different sounds to be selected for each account.

* Move defaultNotificationTone into AccountSettings.
