• css/default.css: fix the problem where all td's inside div's with
  text-align: center on them were getting centred. The temporary fix is
  to tell all td's that they are left aligned again and override it for
  td's inside tr's with row-category class but this seems like a hacky way
  to do this and I've never had these problems on any other site so there
  must be a better solution.
