Add cooldowns to commands

[bosukas]

Summary

Add a way of specifying cooldowns for commands.

Preferred Behaviour

The interface for the cooldowns could look something like this:

cooldown {
    user { event ->
        1 Minute
    }
    
    member { event ->
        if (event.author.id == 332947254602235914) {
            30 Seconds
        } else {
            1 Minute
        }
    }
}

Just another idea of how this can be structured in a command

cooldown { bucketType -> 
    when {
        bucketType.CHANNEL -> {
            15 Seconds
        }
        bucketType.USER -> {
            30 Seconds
        }
        bucketType.MEMBER -> {
            if (event.author.id == 332947254602235914) {
                30 Seconds
            } else {
                1 Minute
            }
        }
    }
}

While I do think that cooldowns are a very valuable thing in a framework like this, I'm not currently in a position where I know how to implement them - I'm going to need help with this one

[gdude2002]

The pull request that would have solved this (#191) hasn't been touched in five months, so I've been left with little choice other than to close it. Perhaps in the future, someone else could have a look at getting this implemented.
