  - The django app name 'journal' has been changed to 'journals' to be

- Migrations were in an odd state because this feature branch had been
  rebased from master many times over the course of months. Clean up
  included:
  - Changing name of 0031_journal_product_class.py migration to
    0032_journal_product_class.py so there wouldn't be two migrations
    sharing the same number
  - Regenerating all the auto generated migrations
