AvailableDisplays marked as Obsolete - no equivalent available in DisplayDevice

This code has been tagged as Obsolete and generates a warning for code that produces no warning using OpenTK 1.0:

        // Summary:
        //     Gets the list of available OpenTK.DisplayDevice objects.  This function allocates
        //     memory.
        [Obsolete("Use GetDisplay(DisplayIndex) instead.")]
        public static IList<DisplayDevice> AvailableDisplays { get; }

Without this method, there is no way to enumerate over the number of displays present on a system (or get a DisplayDevice.Count). Suggest retaining, or adding a property or method that provide the number of displays.
