Stylesheet: better print theme, simpler dark theme

- Better print stylesheet, now with a file dedicated just for print
  style improvements.
- Hide extra stuff in print.
- Bring back navbar for print because it also tells users the current
  section and the site name.
- Dark theme: make superscripts bold instead of using a higher-contrast
  color.
