dumpscript wish: Order by ForeignKeys

[GoogleCodeExporter]

I think it would be a nice addition if dumpscript could order the models by
ForeignKey relations before dumping, so MySQL won't cry about fields which
are still Null (because the relations get setup later on in the script..
too late :/)

Some code could perhaps taken from http://www.djangosnippets.org/snippets/662/
