feed.xml link tag uses a relative path, breaking RSS detection on some pages

[oznogon]

News articles are published to an Atom feed at https://mixxx.org/feed.xml, but in HTML across the site it links to a relative path:

    <link href="feed.xml" type="application/atom+xml" rel="alternate" title="Mixxx Atom Feed" />

This breaks RSS feed detection and links on, for instance, individual news articles because there's no feed.xml at https://mixxx.org/news/feed.xml.

Steps to reproduce:

1. Go to mixxx.org or build the site locally and serve it.
2. Go to any news article.
3. View page source, or click the "Feed" link under "About" in the footer.

Expected behavior

The link or link tag points to /feed.xml.

Observed behavior

The link or link tag points to feed.xml, which results in a 404.

Should be fixed now, thanks for reporting.
