Subject: [PATCH] Unify `link` tag for RSS & Atom into `$url` property (#20)

In rss we have tag <link>https://example.com/articles/some-amazing-article</link>,
but in Atom we have <link href="https://example.com/articles/some-amazing-article"/>.
So, lets extract it from href attr & put into `url` property.
