* When logging back in, check if we missed any conversations in any channels. Bridge up to 49 missed messages per channel.
* If more messages were missed, only the latest missed message will be posted. TODO: Consider bridging more, or post a warning when skipping history?
* This can ONLY detect new messages, not any other kind of event. Any missed edits, deletes, reactions, etc will not be bridged.
