Update icon for iOS 7

[auerland]

Please, update the icon for iOS 7, the golden frame around it looks old-fashioned and ugly; there is even a thin black outer aura when displayed on light background. Yes, I know this is very picky, especially considering the outstanding quality of the game, but I paid a lot of money (even bought all add-ons!) and I want it "perfect".

Thanks in advance for listening!
