Extend cookie consent settings

[martinbira]

To further enhance the cookie consent form and allow the visitor to view all available cookies directly, while not requiring the site author to perform an override of the consent.html-partial, I would like to propose an additional setting that would allow for this.

Suggested addition to settings in mkdocs.yml:
show_cookies

Suggested change in consent.html:

<input type="checkbox" class="md-toggle" id="__settings"{% if config.extra.analytics.show_cookies %}checked{% endif %} />

Thanks for suggesting. However, it makes the "Manage settings" button obsolete, because why would a visitor want to toggle the settings if they are visible anyway? We could maybe default to "always show them, when no button to toggle the settings is included".

Yeah, I thought about that too and that sounds like a good solution!
