When entering the schedule (for PHP Yorkshire), I wanted to add the registration, lunch and after party slots so that people could see them on the schedule and know what's happening. However these require a track - they're not in a track, they're in the breakout space and if I add a "fake" track for them, the grid layout goes very peculiar!

Track should always be optional, so that I can add talks into tracks, but also add other events that aren't in a specific track.
