red thumb option for coop games

Quite often on Hanabi (and maybe also on other coop games), some players make obvious losing moves when you don't play as they want.

There should be an option "losing on purpose" when red thumbing them.

I truly agree with this.

I used to choose the "Help the enemy team" as a fallback.
