#321 Bug Fixes For Issues Found Though Manual Testing

[Al von Ruff]

• common/recognizeddomainClass.py - Added missing import of IsfdbFieldStorage.
• mod/submitref.py - Moved MYSQL_CONNECTOR() call to the outside of the loop.

• edit/find_dups.py = translate() call to (otherwise crashes python3):

  if PYTHONVER == 'python2':
  title_title = title_title.translate(str.maketrans("",""), string.punctuation)
  else:
  title_title = title_title.translate(str.maketrans("", "", string.punctuation))
