Light-themed GitHub toolbar

GitHubLightToolbar.md

GitHub.com recently changed its header (toolbar at the top of every page) to a dark theme, which sticks out light a sore thumb against the rest of the page. Below is CSS to approximate the old theme. A browser add-on like Custom Style Script can be configured to inject the CSS into all pages served from the github.com domain.
