…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

This new optimization is currently disabled by default so you can test it and give us feedback.
To enable it, add #define ENABLE_SDWEBIMAGE_DECODER and to not forget to add SDWebImageDecoder class

…do not prevent memory caching (fix: #24)

Added UIButton+WebCache category

The -cancelForDelegate: method was working for downloads but not local cache checks. Add some new machinery to keep track of pending cache requests and only message the delegate if it hasn't since requested cancellation.
