Tweaks to layouts and styles
Make space for GitLab Runner
If the breadcrumbs has only one element don't display it
Remove first level nav nesting and add the h1 as a nav title. Moved ToC to the right (a future MR will have top level quick links sidebar on the left - this MR has the CSS for it but not the template changes).
Added middle break point, in the future the left quick links sidebar will be hidden.
Closes #106 (closed)
