The main motivation behind this is simplicity and correctnes, but the new small config library is also faster:

This is an improvement over the `readfiles` shortcode in that it allows to insert content files that contain shortcodes themselves.
This new shortcode is used to fix a regression introduced in https://github.com/gohugoio/hugoDocs/pull/1442 (`new-in` shortcode was not rendered as intended).
And we have taken great measures to limit potential site breakage:
* For `disableKinds` and `outputs` we try to map from old to new values if possible, if not we print an ERROR that can be toggled off if not relevant.
* The layout lookup is mostly compatible with more options for the new `term` kind.
That leaves:
* Where queries in site.Pages using taxonomy/taxonomyTerm Kind values as filter.
* Other places where these kind value are used in the templates (classes etc.)

This commit adds the fast and CommonMark compliant Goldmark as the new default markdown handler in Hugo.
If you want to continue using BlackFriday as the default for md/markdown extensions, you can use this configuration:
```toml
[markup]
defaultMarkdownHandler="blackfriday"
```

The image processing examples are rendered within containers with a
'nested-img' parent CSS class, which by default makes images responsive
by resizing them to the size of their containers.
That doesn't work well for the examples as the small images end up
stretched.
Since there can be other images in the same 'nested-img' context, we
keep that class in the parent and set the example images width to auto,
such that they will render with their actual size.
On small screens, larger images will still be sized down via the
max-width property.
Fixes#812
