three small changes to the template

1. Tweaked the refs.bib work in the makefile so that it removes the
   refs-cleaned.bib intermediary step and so that it only rebuilds the
   refs when it needs to.

2. Tweaked the article-2 stylesheet so that subsubsection headers are
   not smaller than normal text.

3. Changed the list rendering so that it's smaller (firmlists).
