This push fixes two errors :

    The script was failing if you dumped a table without "id" column.
    The script wasn't doing anything if it was passed a "--all" argument.

This push also updates with latest Django 1.6.x stable dumpdata.py merge.

See https://github.com/fastinetserver/django-dumpdata-chunks/pull/1

Also, allow_syncdb calls replaced to allow_migrate for django 1.7
