Add option to add global links to footer

[Quintus]

Hey,

I've just discovered klaus and it really looks like the kind of Git viewer I'd like to use. However, in the EU the GDPR requires to have a link to the "privacy policy" on every accessible web page. For that, I can manually edit templates/skeleton.html, but it'd be nice if klaus supported adding links to the footer without modifying its source code, e.g. by reading a linklist from an environment variable or similar.

Thanks for raising this.

I'd like to see this implemented as a more general way to override templates, not as a specific option to add footer links.

Happy to take any PRs :)

I'd also like to have a custom footer for my own klaus instance:

I will try to work on this. Let me know if there is anything updated I should know before I submit a PR.
