Python 3.1 Security Release

Carlton: Python 3.1 came out, you and Marius did all the hard work for that. There was a strange behavior of make in Python 3.7 to not set the permissions of intermediate directories that it creates. And then so when you run collect static, whatever, you had to make sure that we were saying the correct permissions. It's not particularly high impact one. Carlton: If someone's got access to your file system, you've probably got bigger problems already.
