Subject: [PATCH] If nil is given as URL to setImageWithURL:, set the image to
 the placeholder image (or nil if no placeholder)

This is the recommanded way clear an image for reuse (as a UITableViewCell for instance). Calling setImageWithURL:
with nil URL will have the effect to cancel an eventual currently in progress download of a thumbnail for this UIImageView.
Affecting the image property directly won't have this effect and may lead to image being re-affected once download is completed.
