Correctly utilize <content:encoded> and <description> tags according to:
https://stackoverflow.com/a/54905457https://www.rssboard.org/rss-profile#namespace-elements-content-encoded
If there is a summary, show it in <description> with the content being in <content:encoded>. If there is NO summary, put the content in <description>.
Also, I added a custom "summary"/disclaimer for progress update blogs to clarify that the HTML of update blogs really is not compatible with readers but should be viewed in the Webview.
