futurize: shebang and # encoding lines are pushed down by a __future__ import

[edschofield]

A module beginning with a line like these::

# coding: utf-8
# encoding: utf-8

(the last one as in django-mezzanine) or a script beginning like this::

#!/usr/bin/env python

is currently converted by futurize --stage2 into this::

from __future__ import unicode_literals
# encoding: utf-8

or this::

from __future__ import unicode_literals
#!/usr/bin/env python

This is broken.

Fixed in v0.12.
