Custom inprint link

[CubicrootXYZ]

Allow to set a custom "inprint" link at the bottom of the page to be able to fulfill legal requirements in some countries.

This could be solved by an environment variable containing the link, if it is set a text inprint & data protection is rendered at the bottom of the page pointing to that link.

It is possible now to set a custom "About" section but that unfortunately does not match the legal requirements in my country. A imprint and privacy policy needs to be reachable from every single page.

I'd love to see an option to add a custom link in the footer section.
