Cell consistency

Mostly closes #25 

I made it so that the padding around "Break" is more consistent, however, the major issue with the talk cells is whether or not the talk title is one or two lines.  Given that It's not very easy to define dynamic `UITableViewCell` heights, I'm not going to fix that issue.

Cells with a 2-line title will have the same padding as the "break" cells, but one line titles will not.
