Adds a "1-Click Approve" button to the sidebar of the PR homepage.

I got tired to going to a PR, clicking "Files changed", "Review changes", "Approve", "Submit". This reduces a 4-click process down to 1.

See this revision for the sidebar button. The latest version has the button in the Files Changed tab.

Technical notes:

• The "files changed" tab doesn't exist in the DOM until you click it, so we have to switch tabs before we can submit the review.
• I hate using timeouts to add content to the DOM. I saw someone listening for pjax events, but that didn't work for me. Maybe GitHub changed their event names.

The button has been moved to the Files Changed tab:
