A bit more padding-top for unread entries count badges in feeds.
Limit the width of entry titles when closed. Excess text is cut and an ellipsis (...) is appended.
Use margin-top instead of padding-top to move unread entries count badges a bit downward.

padding-top makes the badge itself look taller, even if the number inside is moved where we want it.
Put "mark as unread" button above title, in entry body.

This looks better if the title is very long (we don't truncate the title here, even if it's very long this is the only place where it is displayed completely). Also added some margin to unclutter components.
