Reaction Triggers#146

Would be cool if similar to autoresponders, mimu can have the trigger as a reaction instead! For example something like

.re + :emoji: | messagelink | {addrole: @role} {embed} you reacted!

So it would still support variables. The messagelink part would be which message mimu would sense the trigger from, sort of like reaction roles. But instead of just being able to do reaction roles with it, we can do a lot more! For example, currency commands can also use this, like

.re + :emoji: | {range: 100-200} {modifybal: [range]} you chose to do this! You earned [range] currency.
for interactive ars this would be a good addition.

It can also be connected to an ar, maybe. Like a new variable : {reacttrigger: :emoji:} and the .re with trigger as that emoji will be attached?
