autojump by 林炳权

In OSChina, Gitee, Zhihu, Juejin, Jianshu and CSDN websites will jump to
third-party links without feeling, which can save a lot of time.

## Test

Use this plugin to automatically redirect to third-party links. The following
five links for test redirect to `https://bing.com`.

```
https://www.oschina.net/action/GoToLink?url=https://bing.com
https://gitee.com/link?target=https://bing.com
https://link.zhihu.com/?target=https://bing.com
https://link.juejin.cn/?target=https://bing.com
https://link.csdn.net/?target=https://bing.com
https://www.jianshu.com/go-wild?ac=2&url=https://bing.com
