Show author of a post in the feed list

IMHO it is interesting to see the author of an entry right in the list. Truncated to 35 characters as the feed title is.

Do you follow the guidelines?

My main concern with this change is the layout can get pretty crowded when using a smartphone (especially when having multiple authors).

I do understand that. Though, on small devices the line breaks anyway with longer feed titles. What about a checkbox in the settings for this? I am not sure whether I will soon find the time to figure out how to implement that, though.

Should truncation happen with CSS instead of actually chopping the markup?

Are you asking me? I don't know.

This PR is just about showing the author of a post at all. I tried to keep the code base as similar as possible to the rest of the code and do not intend to alter/replace/improve code design in general.
