pylint: upgrade to 1.3.1
The current pylint is very old at this point. Pull in the latest version
as it supports a lot more features. Also need to fix the pylint wrapper
to actually update sys.path to use the local modules.
This will trigger new warnings in files, but they look like legitimate
issues that should be fixed at some point.
