Move or eliminate contents menu in print and mobile style

[ausmeyer]

The print and mobile stylesheets have the contents section between the normal sections and the figures. In mobile, it seems like it should be either before or immediately following the abstract. In print, it seems like it should be removed altogether.

Either way, the current position sort of defeats its function.

Good point, the contents probably shouldn't be there in the mobile view either - I'll remove it (and maybe restore it in a hidden menu at some point).
