script for automating pep8 checks.

On ubuntu/debian install these tools...

   sudo apt-get install pylint pyflakes python-setuptools python-pip
   sudo pip install pep8

then run from blenders source dir...
   python release/test/pep8.py

This searches for the comments "# <pep8 compliant>" and "# <pep8-80 compliant>", running the checking tools on these scripts only.

* some minor pep8 corrections too.
