quoiFeur game doesn't mute correctly

[neolectron]

Problem

The quoiFeur game has 1/20 chance to respond with coubeh, it mutes you whenever it happens.
The muting strategy goes with adding a role Muted to the user, which we remove after 15min.
This have many edge-cases such as:

• one time, the role was deleted and not re-created (cache miss?)
• it makes uses of setTimeout, so when the bot reload we have to clear the role
• Moderators are most of the time above the muted role, so it doesn't work for them
• We have to keep track of a role, give it some defaults, etc..

Solution

Use native timeout feature by discord (found by @smaiill on discord, thx).
It would solve many of the issues above, while also simplifying the code.
Here is the link to discord.js documentation for that.

Drawbacks

I think there is no such thing as beeing timeout in only one channel.
But considering the low duration of the timeout, and the amount of benefits, I think it's a good tradeoff.
