Feature: Replicate reactions

[sinus-x]

Quick description

Replicate reactions from one server to others.

Long description

Because the text is not changed, we can use .history(around=5) and look for the messages on all of the channels and match them by their content. Then we can duplicate the reaction.

This of course won't replicate the author or number of reactions, but it can try to add the feeling of reactions.

There may be some kind of filter, no one cares about reactions from ten scrolls up the chat.
