Pass image URL in completion blocks - step 5:
- deprecated all UIImageView(WebCache) `setImage*` methods. Replaced with `loadImage*` methods that use the `SDWebImageCompletionBlock` as completion block type - created WebCacheDeprecated category on UIImageView (to avoid collisions, we didn't name it Deprecated) - replaced the usages of the deprecated items with the new ones
