PyPI package does not export version correctly

[drjerry]

I have successfully installed the 1.0 package using pip install, but it is not reported by freeze:

$ python -c "import consistent_hash"
$ pip freeze |grep consistent_hash
$

Also, possibly unrelated, the package does not export its version:

$ python -c "import consistent_hash; print consistent_hash.__version__"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: 'module' object has no attribute '__version__'

Obviously this is minor, but this causes issues with configuration management systems (like Puppet) which verify presence of Python packages using pip freeze.

@yummybian ping, 1.0 also doesn't match the version set in setup.py of master
