Automatic site specific feed search for popular sites (Youtube, ...)

[vackosar]

I spent some extra time finding out how to subscribe to a Youtube channel. In the end it could be automated: https://www.youtube.com/feeds/videos.xml?channel_id=UCIHdDJ0tjn_3j-FS7s_X1kQ

There are probably many popular websites that have some kind of specific behavior like this. Would you consider adding support for Youtube and consider similar approach for other sites? The approach could be:

• try standard way to find feed
• try site specific trick if available
