Remove the dirty hack of storing the helper into the first subview of the UIImageView and prevent duplicate downloads of the same URL The helper (now called manager) is now handling the mapping between the UIImageView and its downloader. This way we don't polute the UIImageView, and don't remove its capability to have subviews. This change removes the automatic handling of image placeholder. The placeholder image can be passed as second argument of setImageWithURL:placeholderImage: The manager now handle duplicate downloads for the same URL gracefuly by sharing the same downloader for all requestors. Finaly, the manager handles URLs which can't create an image (HTTP error or invalid format) by flagging them so it won't retry to download them again and again.
