Title: Add diff range link next to commits in PR view

To test
-----

* Install the extension
* Visit a PR page with multiple commits. You should see arrows next to all commits except the last. http://cl.ly/image/403N3B0m3D2V
* Clicking an arrow should take you to the diff between that commit and the last one in the PR
