draft instructions for technical reviewers of the CSS Properties pages

Hi, everyone: 

I had the action item to draft instructions for technical reviewers of the
CSS Properties pages. I filed a task and completed it:

http://project.webplatform.org/content/issues/43

Any feedback appreciated. But would you please use the commenting feature in
project.webplatform.org?

Thanks!
