Design a default screen when no React instance is detected

[sebmarkbage]

Currently we don't show the React tab if we can't detect React. We should have a better default screen that explains how you can get React and how to make it work with DevTools on your page.

I like how it currently doesn't spam the devtools tab as long as you are not on a React enabled page.
I could see it useful if there are scenarios where the devtools would fail to detect React on the page.

@sebmarkbage By "default screen", do you mean a webpage that is automatically loaded into a new tab on "first run" (and possible on extension upgrade), with basic instructions on extension usage?

If so, I agree, this would be a great place to inform users about why they might not be seeing the React tab. (#28)

It probably wouldn't be visible on first run if there already is a React instance on the page.

@sebmarkbage I was referring to something that only appears once, when the extension is installed (could also appear when the extension is updated). I think you are talking about having the "React" tab in developer tools always visible. I agree with @kassens that this would not be ideal.
