Fixed some smaller bugs and slightly improved formatting of commit entries.

- scripts/schhist2web: when starting, remove html_* and pdf_*
- scripts/schps2pdf: corrected quoting of sheet title derived from file
  name (produced many error messages and caused garbled titles in the
  overall schematics)
- scripts/schhist2web: indent date in commit entry such that it's flush
  with the author
