Title: Adds progress block to UIImageView+AFNetworking

I needed progress from an image download. This was the easiest way I saw to do it, and seems to fit with the established model of having success/failure blocks.

If there is a simpler way or some other recommended way, please let me know...I have no doubt I could be missing something! (I know that there is a goal of keeping things very simple inside the library, to avoid bloating)
