This is a feature/fix to improve notification behavior when we receive
over 3 messages.
SnoreNotify prevents over 3 notifications from being displayed before a
user clears the notification. This is presumably to avoid infinite
notification spam.
Unfortunately this results in the notifications just coming in _after_
the user clears them. This means if there are 100s of messages built up
the user has to clear their notifications N messages / 3 times.
This feature/fix folds all notifications into a single notification
representing the current qTox notification state. See
notificationgenerator_test.cpp for what the new messages look like.
