Support for module:content

[deian]

I added support for content:encoded that is pretty widely used to integrate HTML content in RSS feeds.

I'm currently using it in LearnByHacking. See for example https://www.learnbyhacking.org/posts
and the corresponding code: https://github.com/scslab/lbh

I can add support for ther other stuff mentioned in the module (e.g., content:item), but I don't think they're as widely used as content encoded.

[Sorry for bumping the version, I can drop it if you wish]

Thanks for the patch but I'm not sure I should merge this since in 2006 Bjorn removed (c39dffc) the ContentEncoded constructor from rss with the explanation that the descriptor tag is the recommended way to include HTML content. Note that I'm not an RSS expert. Has this recommendation changed over the years?

I am not an RSS expert either, but judgin from
https://developer.mozilla.org/en-US/docs/RSS/Article/Why_RSS_Content_Module_is_Popular_-_Including_HTML_Contents
and inspecting RSS feeds on Wordpress (https://donsbot.wordpress.com/feed/) it seems like people are still using it.
Though including it in description as CDATA is common too, so I understand if you don't merge this.
