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).
(1) by default, use slightly smaller section headings font style
(2) by default, use "real" \scshape w/o \MakeLowerCase
(3) add commented out code to turn on (sub)section numbering
