project.py: Cleaned up pylint/pep8 violations

I noticed when running pylint (as the SUBMITTING_PATCHES file directs)
that there were a number of violations reported. This makes it difficult
to see violations I might have introduced. This commit corrects all
pylint violations in the project.py script.

This script now has a pylint score of 10.0, and no violations reported
by pep8.
