PYPI package seems to have wrong preprocess.py dependency

[utsekaj42]

I discovered today that installing with pip in Python 3 results in this error which is not present in the "doconce/preprocess.git". Perhaps the dependencies just need to be updated on PYPI.

The PyPI package hasn't been updated in a while. I've uploaded 1.4.10 now. Unfortunately, I do not have the permissions to update the preprocess package on PyPI, which is really outdated. Consequently I changed setup.py so that DocOnce will not pull in (an outdated Python 2 only version of) preprocess automatically.
