实现思路也比较简单，丢图片->丢HTML->丢JS，然后加载！
下载压缩包： add_smilie__20180114.zip ，直接解压丢入即可。然后，post.jade 加载
+post.comments_as_html()
include smilies.jade
+h.load("/template/include/smilies.js")
附赠给评论添加楼层标识：
.comments{counter-reset:comment-floor}
.comments>.comment{position:relative}
.comments>.comment:before{content:"#" counter(comment-floor,decimal);counter-increment:comment-floor;font-size:32px;position:absolute;top:15px;right:20px;color:rgba(0,0,0,.08);font-style:italic;font-weight:700}
