v2.0.2...v2.1.0

- Allow `no_native_review_since` tag (by @cl8n)
- Fix errors for section links within news posts
- Add support for GitHub link checking as suggested by clayton,
  i.e. links like https://github.com/ppy/osu-wiki/tree/master/news or
  https://github.com/ppy/osu-wiki/blob/master/CONTRIBUTING.md#testing
  are checked locally
- Fix links like `![](/img/cat.png)` being ignored (when it should be
  `![](img/cat.png)`
- Improve error display a bit (no more "wiki/../news" nonsense, etc)
