功能：给窗口增加翻页按钮
作者：后知后觉 2011-8-31
说明：请自备鼠标脚本（whbm）
把此核心部分放在 Window_Base 的下面最好和他挨着
把需要有这样效果的窗口将其父类设置为 Window_MouseSelectable
然后在相关 Scene 增加对窗口实例的 hzhj_state 属性判断
如果为 1 则是向上翻页对窗口实例掉用 up_page 即可
如果为 2 则是向下翻页对窗口实例调用 down_page 即可
还可以在窗口初始化后调用 make_rect(x1, y1, x2, y2)
参数可以省略省略则为默认值这是在设置翻页图标的位置
是相对于本窗口的坐标位置
如果你的窗口在运行中进行了移动（x y变化了）
或者是窗口大小被改变了（width、height）
都最好再调用一次 make_rect 来更新数据
