Compiling without PCH

[ndfred]

I've been using iCarousel with iOS 5.1 on the latest Xcode without PCH files (to get around Xcode syntax highlighting bugs) and it broke the build: the QuartzCore headers are included after the CGRect typedef is made, resulting in an unknown type name 'CGRect' error:

My fix just includes the QuartzCore headers a few lines earlier, which should be harmless and fix the bug.

By the way thanks for this great piece of software, saved me a couple days of work!
