Move toplists from inline styles to less-file

Also align people without gravatars similar to people with gravatars, hopefully
to address marcus's feedback from a while back :) The page has a little bit less
air, but it fits better on a portrait ipad resolution, with two items on each line.

This hopefully addresses the concerns in #392
