 * On iOS 7 SKStoreProductViewController can cause a crash if the application does not list Portrait as a supported
 * interface orientation. Specifically, SKStoreProductViewController's shouldAutorotate returns YES, even though
 * the SKStoreProductViewController's supported interface orientations does not intersect with the application's list.
 *
 * To fix, we disallow autorotation so the SKStoreProductViewController will use its supported orientation on iOS 7 devices.
