	Описание:
	Отображение сообщений с текстом на экране игры.
 
	Инструкция: вызвать скрипт
	add_notification(text, time = -1, icon = 0, icon_id = 0, position = 1, window_color = 0)
	text - текст сообщения
	time - время отображения в секундах 
	(если time = -1, то рассчитывается исходя из длины текста)
	icon - 0 (ничего), 1 (balloon), 2 (иконка)
	icon_id - индекс иконки (0 - ничего)
	position - 1 (сверху), 2 (по центру), 3 (внизу)
	window_color - 0 (черный), 1 (белый), 2 (зеленый), 3 (красный), 4 (синий)
