Interlinks and filters on gh-pages

[mcarton]

Copied from https://github.com/Manishearth/rust-clippy/pull/1091#issuecomment-240889966.

---

• Go on https://manishearth.github.io/rust-clippy/v0.0.84/
• Set filter “break”
• Open “wrong_pub_self_convention”
• Click on the first link: “This is the same as wrong_self_convention, but for public items.”
  ⇒ Nothing happens.

Expected result: the filter vanishes and the page jumps to the lint.
