DM users with original message when mods reverse a decision to delete

[DecentralizedDan]

There will be times when the decision to delete a message as spam etc. will be reversed

• When that happens, Bouncer will DM the user with an explanation of what happened,
• And with the text of the original message
  • This will make it easy for the user to copy and paste the message into the channel from which it was deleted
  • It will also warn users that, to ensure the message doesn't get deleted again, they should check to make sure that uf they repost it, it should be in the same channel (in case it will violate a channel-specific policy etc.)
• We will explain: "If you choose to repost this, Bouncer will reply with a message that it was mistakenly deleted before", as per #121

Closed bc no good way to DM a user who hasn't friended Bouncer

• Also low priority
