Set default arena/normal type by game not overall

[Jontia]

I'd like to be able to select the game type as either arena or normal mode on a per game basis so I don't have to flip backwards and forwards when queuing up a bunch of turn based games.

For games that I dislike the Arena settings, or ones I enjoy but am no good at, I'd like normal mode to be the permanent setting while I queue up for Arena games for those I'm trying to be competitive at.
