Suggested: style links with underline

Making this change takes a default installation from a Lighthouse score of 92 to 96.

Update includes/templates/bootstrap/css/stylesheet.css with

a {
   text-decoration: underline;
}

Sounds good, but that change will be created in stylesheet_364.css as a browser cache-busting update. Otherwise, any browser cache of stylesheet.css won't have the change.

For whatever reason, the changes I just pushed for this issue didn't 'attach'.
