Add livejs to head for index and pyfile

Add livejs to so that coverage report automatically updates.

CI is stuck at an install error for windows; seems like this is unrelated to my code change:

Hi, thanks, I hadn't heard of livejs before. But I don't think I want to always use it in every HTML report. Maybe we can solve this similarly to extra_css? A setting that lets people specify extra scripts to include in the HTML? Then you could use livejs in your settings, and all of your HTML reports would include it.

What do you think?
