copycat of sahat/hackathon-starter，抄过来改改。
模板引擎换成 swig，比 Jade 好用多了，本地邮箱登录注册功能完成。
第三方邮件发送服务可以用 Postmark 和 Sendgrid，Mailchimp 没看懂怎么用，前面两个都有 Node.js 的 API 用，可以加上，用户注册和修改密码需要发邮件，本地邮件发送用 Nodemailer，另外一个就是可以都写成 API 来用。
GitHub 登录搞定了。
Nodemailer 太麻烦就不搞了，就用 Postmark 和 Sendgrid 好了。第三方登录只加了 GitHub，Google 要报错，也不搞了。还有个问题就是 Node.js 用 PostgreSQL 也是可以的，要可以的话我就想给迁移过去，MongoDB 实在不好用。
