Speaker name on Schedule

As an attendee of BadCamp, it would be useful information to have the Speaker and possibly the Sponsor of the session in the Session Teaser on the Schedule page. This would help me make a more informed decision if I want to attend that session or not.

Speaker added on to Sessions and can be seen on LIVE; position will be changed first item in list of details to match Trainings and Summits in forthcoming PR.

Leaving Sponsor as-is for now, in part due to lack of icon, but mainly for @sean-e-dietrich to make the call here...
