Title: Remove GCD retains/releases for iOS 6.0/OS X 10.8 and above

GCD queues are now handled by ARC in IOS 6.0/OS X 10.8. The dispatch_retain/dispatch_release calls cause the build to fail against these platforms.

This adds a define to conditionally remove the calls for these platforms, and also updates Reachability, as the same type of change is now present in HEAD.
