Message update

[2byrds]

We need a way to have messages that are updatable, so instead of spamming the user chat with the same message over and over that has a new time stamp each time (like 'You have no new messages'), we need to be able to replace a previous message with the same message with a new time stamp.

Do not use logging level to achieve this, the previous message needs to literally be replaced by the new message.
