Schedule of talks

I would've preferred to get the Friday sessions and workshops within the same table body and rows, but the times don't match up nicely. The only way I can think that would work is to stop using tables and use fixed height elements instead.

I think we should go with this for now and if it bothers us, look at changing it afterwards. Let's get this published.

@roidrage If you agree, feel free to merge and push before I wake up. Otherwise I'll see you guys in the morning. :smile_cat:
