Title: Updated animations to use blocks introduced in iOS 4

Updated PullRefreshTableViewController.m to use the new style animations introduced in iOS4. Per the Apple documents on UIView, use of the old style animations is discouraged in iOS 4 and later and they suggest using block-based animation methods instead.
