Work search: have parent/child sessions look better

[mdlincoln]

Child sessions should look like full work cards, wrapped by a parent.

@scottbot how about this?

It's just cosmetic - if the child papers match the same query as the parent papers, they'll all show up in the results. But at least now you get the author names in there.

I appreciate the work you put into this, but if it's not a full solution (more than just cosmetic), I think it's better to keep it as it is, to keep scrolling a bit less onerous for conferences with many multi-paper sessions.

alright, will keep the code unmerged for now
