/**
* - chrome为了安全考虑,设计的不支持js操作加入收藏夹,
* - 火狐23之后开始废止window.sidebar因为不是w3c标注 https://bugzilla.mozilla.org/show_bug.cgi?id=691647
* - document.all 判断IE不够靠谱,因为现在许多浏览器也实现了document.all吗,并且IE11以后(document.all)为falsy
* - 参考 http://stackoverflow.com/questions/10033215/add-to-favorites-button
* - IE 中typeof window.external.addFavorite 为'unknown' [http://www.xdarui.com/archives/203.html];
