v6.6.0 setup.py iteritems() error

[telesphore]

Python 3.6.1 virtual environment (not conda!), Ubuntu 17.04 x64, GPU cuda 8.0...

I believe that you can stop the error at line 157 in setup.py to something like

for k, v in cudaconfig.items():

Error follows

(venv) $ pip list -o
Package Version Latest Type 
------- ------- ------ -----
thinc   6.5.2   6.6.0  sdist

(venv) $ pip install -U thinc
Collecting thinc

This was dumb, thanks --- the Travis tests didn't exercise the CUDA branch, so this slipped through.
