Title: Added Pew (and misc. related changes)

I added Pew and its dependency virtualenv-clone

Since virtualenv-clone depends on tox for its tests, I also tried to see if it was possible to get it working

(updated tox's dependencies: py and virtualenv)

turns out that tox's latest version can be installed, but its tests will still fail
