4.0.0-alpha1

The dependence on SETools 3 has been removed. It is tested on Python 2.7, but development will likely be transitioning to Python 3.3, as the barriers blocking 3.3 have been addressed.

While this is still alpha code, the existing code is fairly well tested, with 73% coverage from unit tests. The core CLI tools, with the exception of seinfo, are nearly complete. The GUI tools have not been started yet.

Warning: If you replace the SETools 3.x on your system, it will break the couple of tools from sepolgen/policycoreutils that depend on SETools (e.g. sepolicy) since the API has changed.
