/*换肤效果*/
/*
本函数调用时请重复调用3次，不然在ie6下面首次更换样式的时候图片无法正常显示,原因不明！参数name必须为英文，每种样式都需要在images文件夹中以name（实际传入的name值）为名新建文件夹，并将相应图片放入其中（图片尺寸、位置和文件名必须与blue文件夹中的图片完全一致）。同时还需要在以下css样式表中添加相应className属性：
1.	public.css文件中的searchBox属性。
2.	public.css文件中的footerlinks属性。
3.	homepage.css文件中的logTabUnselected属性。
4.	homepage.css文件中的tab01Unselected属性。
5.	homepage.css文件中的left_button和right_button属性。
6.	homepage.css文件中的more02属性。
