Deprecate hardcoded footer links in favor or new `footer.links` array for any link and in any order. All of Font Awesome's icons are available for use.
```
footer:
links:
- label: "Twitter"
icon: "fab fa-fw fa-twitter-square"
url: "https://twitter.com/username"
- label: "GitHub"
icon: "fab fa-fw fa-github"
url: "https://github.com/username"
- label: "Instagram"
icon: "fab fa-fw fa-instagram"
url: "https://instagram.com/username"
```
Where it makes sense replace asset paths and navigation related paths with `relative_url` filter.
Leave SEO related `<head>` elements and social sharing links as `absolute_url`.
