Title: Implemented Collapse/Diff for discussions at a PR

I've added buttons to diffs at the Discussion section to make it easier to hide a diff+discussion during a PR.

I've edited the README file to include a link to the Chrome extension I've found in the Chrome Web Store, and uploaded the script to userscripts.org as well, for Firefox/Greasemonkey users.
