Fix check of glossary item

CommonMark doesn't support definition list
and we have to workaround this limitation.

This commit removes the request
that line continuation start with four white spaces
because (1) CommonMark remove the white spaces and
(2) Pandoc doesn't care about it.

    $ pandoc <<EOF
    foo
    :   bar
        continue
    EOF
    <dl>
    <dt>foo</dt>
    <dd>bar continue
    </dd>
    </dl>
    $ pandoc <<EOF
    foo
    :   bar
    continue
    EOF
    <dl>
    <dt>foo</dt>
    <dd>bar continue
    </dd>
    </dl>

consolidate badge classes to swc.css

Thanks to ocefpaf for request that.

Add variable to represent Pandoc

Pandoc had some changes in the last versions.
Having a variable for Pandoc will help
maintainers to handle different versions of Pandoc.

Figures should be centered
and not overflow the screen.

Add article tag as wrap for lesson content

CONTRIBUTING.md: Remove the maintainer references

Because we're going to be storing maintainer information locally in
the README.md [1].

Remove logger name (root) from console messages

Ignore conduct.md and contributing.md. No, really.

(even though the contents are not validated)

tools: Add trailing newlines to files that were missing them

This avoids things like:

  ~$ cat tools/validation_helpers.py
  ...
          return self.is_block(ast_node) and has_heading~$

with your next prompt way over to the right ;).

CONTRIBUTING.md: Use a generic reference name for the issues link

Filling in the list of contributors from the Git history.

See MAPPING AUTHORS in git-shortlog(1) for details on .mailmap.

For both authors I've selected the email address that they've used
most recently.

I haven't configured the copyright blurbs, because we don't have to
use that functionality if we're just maintaining an AUTHORS file.

We're taking advantage of the automatic name detection that landed in
update-copyright 0.6.2 [1], so downstream lesson maintainers won't
have to tweak .update-copyright.conf (assuming they name their local
repository directory appropriately).

Downstream lesson maintainers are supposed to adapt this to point at
their repository's issues [1], so use a reference name that works for
both the lesson-template and downstream repositories.  That way they
only have to update the referenced URL and can leave the reference
name alone.

the class removed are unused as we take advantage of classes provided by
Bootstrap instead.
