Convert nose optparse options to argparse
Convert nose optparse options to argparse

When django.core.management.base.BaseCommand includes 'use_argparse',
then nose's optparse options are merged using argparse's
parser.add_argument in BaseCommand's overriden add_arguments method.

For Django 1.7 and earlier, the current .options method is used to set
the options.

Fixes #178.
