Fabric 2.0: [Errno 2] No such file or directory: 'LICENSE'

Hi,

When installing the recent 2.0 release, the install fail when building wheel:

Thanks for the amazing work !

It looks there is indeed a packaging problem. On PyPI the Python 2 version is distributed as a wheel package while installing from Python 3 downloads a tar.gz that is missing the LICENSE file referred in setup.cfg.

pip as default tries to build a wheel from the downloaded tar.gz and fails for the missing file. Right now the way to obtain a clean install is to pip install --no-cache-dir to force pip to install from setup.py bypassing the wheel build step.

I hope that Jeff will distribute a .whl for Python 3.

Did a stealthy force push due to a minor mishap, but 2.0.1 is now up on PyPI and appears to have the proper universal wheel now.
