Fix liquid variable leakage in navigation components (#1243)
* Refactor nav, breadcrumbs, children_nav

Fix #1118

Improve the modularity of building the nav-panel, breadcrumbs, and children-nav
by making them independent. This also significantly simplifies the Liquid code.

* Fix order of breadcrumbs

* Update breadcrumbs.html

Revert inclusion of single breadcrumb for top-level pages.

* Update breadcrumbs.html

* Update children_nav.html

Revert to the previous layout in the HTML, to allow the use of `diff` to check the built site.

* Update minimal.html

Remove the previously required workaround involving `nav.html`.

* Add docs pages about layouts

The aim of the initial version of these docs pages is to illustrate the difference between the default and minimal layouts.

* Update CHANGELOG.md

# Layout
You specify the layout for a page in its [front matter]. Just the Docs has a `default` layout with a sidebar, used for almost all pages in the theme docs, and a `minimal` layout that omits the sidebar.
{: .fs-6 .fw-300 }
## The layout concept
See the [Jekyll docs page about layouts] for an explanation of the general idea of layouts and how to specify them.
You can use [Jekyll's front matter defaults] to specify the same layout for many pages.
## The `default` layout
This page uses the default layout.
It is a *responsive* layout: on medium and larger width displays, it displays a sidebar, including a navigation panel; on smaller width displays, the sidebar is automatically hidden under a button.
Each child (and grandchild) page of a top-level page has so-called *breadcrumbs*: links to its parent (and grandparent) pages. It shows the breadcrumbs above the main content of the page.
Each page that has child pages generally has a list of links to those pages (you can suppress it by `has_toc: false` in the front matter). It shows the list as a *table of contents* below the main content.
## The `minimal` layout
A child and grandchild page of this page use the minimal layout. This differs from the default layout by omitting the sidebar -- and thereby also the navigation panel. To navigate between pages with the minimal layout, you can use the breadcrumbs and the tables of contents.
## Other layouts
Just the Docs has further layouts: `about`, `home`, `page`, and `post`. Currently, they are all based on the `default` layout. See the [Jekyll docs about inheritance] for how to customize them.
