给jsimple主题添加代码高亮

周末在家无所事事，想起来博客代码块的高亮支持不是很好，于是根据作者推荐的hipaper去get。
对比了Hipaper和Jsimple老半天有几点发现。

1. Jsimple使用ejs模板
2. Hipaper使用ejs模板，css采用stylus框架。<之前只听说过less和sass,又涨姿势了~~~>

在浏览器端f12审核元素发现两个模板生成的html元素有些区别。然后就花了大量时间去找hexo是怎么把代码块自动解析成对应的html代码的。
后来在hexo群里求助得知由hexo自带highlight插件生成。这位热心的大神顺手帮我搞了高亮的css代码，之后也在jsimple仓库pr了代码。
得到css后依据自己的博客进行些小改动，添加了night版。然后愉快的给博客添加了代码高亮。
注意配置文件这里：

highlight:
  enable: true //开启高亮
  line_number: true //显示行号
  auto_detect: false
  tab_replace:

修改之后生效需要执行

//清除缓存文件 (db.json) 和已生成的静态文件 (public)。
hexo clean
//重新生成
hexo g

这里贴出代码仅供参考：自己改了些东西，不知道适不适用
