Title: Added option to not set the image in the imageView upon completion.

I was using SDWebImage as part of an ```NSOperation``` and I wanted to manually set the image after completion only if the operation hadn't already been cancelled.

I don't know if this is useful for anyone else, but I figured I'd share :)
