C# Class ControlzEx.KeyboardNavigationEx

Helper class for a common focusing problem. The focus itself isn't the problem. If we use the common focusing methods the control get the focus but it doesn't get the focus visual style. The KeyboardNavigation class handles the visual style only if the control get the focus from a keyboard device or if the SystemParameters.KeyboardCues is true.
