ImportError: No module named util.escape

[diphuaji]

This line in requirements needs to be changed: "keyring>=10.1".

The newest version of keyring is 15 and named util.escape does not exist anymore.

So if one follows the instructions an error is sure to bump out:
ImportError: No module named util.escape

I have to install keyring==12.0.0 to fix the problem.
