Supply a {@link PendingIntent} to send when the notification is cleared by the user
directly from the notification panel.  For example, this intent is sent when the user
clicks the "Clear all" button, or the individual "X" buttons on notifications.  This
intent is not sent when the application calls
{@link android.app.NotificationManager#cancel NotificationManager.cancel(int)}.
