Paper chat channel should show a special flair for authors/presenter of that paper

[mattmccutchen]

Currently, there are "Author" and "Presenter" flairs that, as I understand, are supposed to be used by people who have written or are presenting anything in the conference. However, these can be misleading in the chat channel for a particular paper. There, I'd like to see a special flair for the authors and presenter of that paper. The conference-wide flairs could be shown semi-transparent, if at all.
