Random Trade

[Ziloxeur]

Is your feature request related to a problem? Please describe.
It's an idea of new feature that could be added to the bot for more fun.

Describe the solution you'd like
I want you to add a command w.trade/w.t @pseudo or w.exchange/w.e @pseudo that will trade 1 random character from each person of the duo if the second one accept the request by typing yes when he get pinged. I'm not sure about the second part but you could maybe also add a cancel command w.back/w.b that if written by both persons after the trade is done, gives back the characters to each one.

Additional context - optional
Don't forget to select characters that the other don't have to dodge bugs or duplicates characters.
