Add bigger territories sizes

I totally agree with the idea that having the option to choose to play with bigger territories than the ones we have now can only benefit the game.
And I would suggest that the highest size available could be at least 90.

I had this idea after playing the Aurigan Summer Contest. On that map I've had some of the best games ever, if not the best. I'm quite noob, in fact I haven't even managed to reach first place when the game ended, so i't obvious that I don't have a deep understanding of the balance of the game, BUT I can say that I probably had so much fun cause territories were huge in a huge map and I think most territories were at least 90 hexes.

Since it's not a competitive online multiplayer game and since there are already tons of customizable options for random generated worlds I think reaching 90 hexes territories can only be a plus for the game, even if this option is restricted to 8+ players maps.
