django-admin.py dumpdata fails because it doesn't inherit options_list from BaseCommand

[Matthew Flanagan <mattimustang@…>]

Running {{{django-admin.py dumpdata}} fails with the following traceback:

Traceback (most recent call last):
  File "./manage.py", line 11, in ?
    execute_manager(settings)
  File "/xxx/django/django/core/management/__init__.py", line 163, in execute_manager
    utility.execute(argv)
  File "/xxx/django/django/core/management/__init__.py", line 107, in execute
    self.fetch_command(command_name, argv[0]).run(argv[1:])
  File "/xxx/django/django/core/management/base.py", line 59, in run
    if options.settings:
AttributeError: Values instance has no attribute 'settings'

because it doesn't append its own options to the BaseCommand options_list.

Simple patch is

(In [6081]) Fixed #5375 -- Added base command options to the options registered against dumpdata. Thanks for the fix, Matthew Flanagan <mattimustang@…>.
