Implementing Desktop support for local notification

[mirzemehdi]

If tray is supported then tray notification is shown, otherwise JOptionPane dialog is shown

fun getNotifier(configuration: NotificationPlatformConfiguration.Desktop): Notifier {
        return when {
            TrayNotifier.isSupported -> TrayNotifier(configuration = configuration)
            //TODO for now return JOptionPaneNotifier for not supported platforms
            else -> JOptionPaneNotifier(configuration = configuration)
        }
    }```
