Add support for new \pep, \seepep, excclassdesc markup.

Update processing of module synopsis tables (found at the beginning of
most chapters of the library reference) to reflect changes in the
processing pattern of recent versions LaTeX2HMTL.  Requires most
recent change to SynopsisTable.pm.

This does not fix the module index problem.
