Title: Add post-download block for apply "effects" to downloaded image

I add an extra block parameter in UIImageView+AFNetworking methods to apply any sort of image refinements on downloaded images.
This block will be executed right before set the image inside the UIImageView object and does not effect the cache.

For me, it's very simple but also very useful.
