…n-disk image cache. (Fix #47)

If a cache check is initiated, then canceled with cancelForDelegate: before a new cache check
is started with a different URL but the same delegate, the ongoing disk cache check would still
message the delegate despite being canceled by cancelForDelegate:. This is because it only
checked to see if the delegate was in the cacheDelegates array; it had been removed by
cancelForDelegate:, but added back by the new unrelated cache check. cacheURLs keeps track
of which specific URLs are actually requested by the delegate. If the URL from a completed
disk cache check does not match the delegate in cacheDelegates, the delegate is not messaged
(since we know that request was canceled).

update version check to make #if work for iOS >= 4
