Title: Improvements to the interactive navhelp

Switch the explanations about the navbar to use images so that the page works better on narrow viewports.

It's still not perfect for very narrow windows, although if the window is too narrow, it seems to just force a horizontal scrollbar (which I think is an acceptable compromise.)

I also made one tiny tweak to some Parsons CSS, related to the Bootstrap upgrade.
