edits to CardView.m Card.m and GameView.m for Mavericks

Hi, Alisdair,

I'm just getting my feet wet with git, and your Freecell project is one that I've been tinkering with a little bit this week. It took me forever to upgrade from SnowLeopard even to Mavericks (just in the last couple of months), so I'm also just getting my feet wet with the coding changes that come with Mavericks. Your project is really solid as far as avoiding deprecated code, and I only had to change compositeToPoint: invocations to drawAtPoint: in a couple of files, and adjust a couple of int variables to NSUInteger or NSInteger. This fork of your project now builds without any issues I can detect under Mavericks, in case you want to update. I don't know whether the changes will put any squeeze on a user base with older systems. Cheers, and thanks for creating this project, which has afforded me many hours of entertainment over the years.
