Title: "hello world" conversation between content_script.js and background.js

Visiting wikipedia will invoke a couple of messages to be sent from content_script.js (which runs in the browser) to background.js (which runs in the extension) and back.

My attempt to turn this into fewer commits has only led to it having more commits. Oh well.
