ImportError when using past.translate feature for UserDict import

[khchine5]

Hi,
My code :

from past.translation import install_hooks, remove_hooks
install_hooks(['appy'])
from appy.pod.renderer import Renderer as OriginalAppyRenderer
remove_hooks()

And I has the following error:

File "/home/khchine5/PycharmProjects/lino_fork/lino/modlib/appypod/appy_renderer.py", line 27, in <module>
    from appy.pod.renderer import Renderer as OriginalAppyRenderer
  File "/home/khchine5/.virtualenvs/py3/lib/python3.4/site-packages/past/translation/__init__.py", line 413, in load_module
    exec(code, mod.__dict__)
  File "/home/khchine5/.virtualenvs/py3/lib/python3.4/site-packages/appy/pod/renderer.py", line 26, in <module>
    from appy.shared.zip import unzip, zip
ImportError: No module named 'UserDict'

By looking at past code, I think that it does not consider UserDict change between Python2 and Python3.

Thanks.
