add a clan wars simillar as in goodgame gangster

I think this is a very good idea. Clan wars would make the game more interesting, and maybe you could add an reward for winning a clan war- for all the people in the clan, not just the leader. As a leader of a clan, I want to make sure everybody is treated equally in the clan, and it would be nice for the more less experienced people in the clan to get a reward. I look forward to clan wars if they will be added!
