deleted message notice
Current behavior: when a user deletes a message, it's removed from the channel altogether.
Requested behavior: when a user deletes a message, that message is replaced by "message deleted" as a status message (the same style as "user has joined the channel"). This could be implemented as default behavior, or as a setting.
Reasoning: it can be important for the context of a conversation to see that one or more messages were deleted. A user might have responded to a message that has been deleted, which can change the meaning of the message.

      Hi there, the "message deleted" status message does show when somebody deletes a message - however, the status message is not permanent and disappears when you log out. Would you suggest that the status message should be permanent?
