Tweak presence subscription behaviour & new chat behaviour 

- The "New or updated group chat" message is very spammy, and not even that
  useful for being notified about a new chat you might have missed out on. We
  no longer send that, but we do send something when you get a message for an
  unknown groupchat.
- Presence subscription requests are now only sent if you have a chat open with
  someone, because I got tired of receiving randomers' presence subscription
  requests...
- Presence is now only ever sent in response to a presence probe, or when a user
  updates their status or profile picture. You won't get presence from all
  whatsapp contacts when the bridge connects any more.
