求讀取存檔功能！ - Project1

#===========================================================================
#1、调用方法：$Scene = Scene_System.new(上级菜单索引编号，从菜单进入？
# 从事件进入（false）？从标题进入(false)?）
#
#2、from_event和from_title可以无视，还没弄－－|||
# 要去掉的话改下return_Scene好了
#3、想不出啥了，改了下Window_Help的initialize方法：
# def initialize(x = 0, y = 0, width = 544, heigh = WLH + 32)
# super(x, y, width, heigh)
# end
