start migrating the LaTeX output filter from sed to Haskell
improvements to latex spew filter
take a stab at tracking line numbers when parsing log files
start handling a few overfull hboxes
latex-spew filter: stop ignoring overfull hboxes and add a mode that prints out all the (non-image) files that latex munged during this run
slight refactoring of spew filter: make it so locallyInteresting doesn't have to be mutually recursive with interesting (so that we can plug in different filters more easily later)
pretty-printing in skew filter
fix some really awful overfull hboxes
ignore more whitespace in spew filter
don't remove whitespace after non-dissertation \dissdis's
all overfull hboxes are now either small (<12pt) or unavoidable (on zero-width endofpfmarker boxes)
