Title: Apply some of the techniques from https://caremad.io/2014/11/distribu… … …ting-a-cffi-project/

In particular make sure "nacl._lib" is imported after setup has installed the setup_requires. Otherwise trying to pip install pynacl on a fresh system which doesn't have cffi installed will silently fail because it won't have built the cffi extension module.
