Subject: [PATCH] Make schhist more forgiving if profile or top-level sheet is
 missing.

- schhist/gitsch2ps: issue a (fatal) error only if .pro and .sch are missing
- schhist/gitsch2ps: exit with success if only one of .pro and .sch is
  missing
- schhist/schhist2web: skip commits for which no Postscript was generated
