Adds methods to UIImageView supporting asynchronous web image loading:

using SDWebImage;
...

const string CellIdentifier = "Cell";

public override UITableViewCell GetCell (UITableView tableView, NSIndexPath indexPath)
{
	UITableViewCell cell = tableView.DequeueReusableCell (CellIdentifier) ??
		new UITableViewCell (UITableViewCellStyle.Default, CellIdentifier);
	
	// Use the SetImage extension method to load the web image:
	cell.ImageView.SetImage (
		url: new NSUrl ("http://db.tt/ayAqtbFy"), 
		placeholder: UIImage.FromBundle ("placeholder.png")
	);

	return cell;
}

It provides:

• UIImageView and UIButton extension methods adding web image loading and cache management.
• An asynchronous image downloader
• An asynchronous memory + disk image caching with automatic cache expiration handling
• Animated GIF support
• WebP format support
• A background image decompression
• A guarantee that the same URL won't be downloaded several times
• A guarantee that bogus URLs won't be retried again and again
• A guarantee that main thread will never be blocked
• Performances!
• Use GCD and ARC
• Arm64 support
