      Compile messages hook for django_productline, this task checks for the activated languages
      in settings.LANGUAGES. It runs the standard django compilemessages management command with the -l parameter.
      Example language setting:
          LANGUAGES = [
              ('en', 'English'),
              ('de', 'Deutsch')
          ]
      Remarks:
          - Each argument for the management command MUST be a single list item, e.g. ['compilemessages', '--locale', 'en']
          - The compilemessages command MUST be executed in the projects root dir, so the CWD is adjusted before running this command.
