Publish wheels to PyPI

[ksmyth]

Source distributions run setup.py. OMPython's setup.py does not install OMPythonIDL if importing omniidl and omniORB fails. This happens when one creates a new virtualenv and does pip install OMPython

Publishing a Wheel would avoid this issue. Try pip install --extra-index-url https://pypi.metamorphsoftware.com --log log.txt OMPython in a new virtualenv. The .whl is installed and OMPythonIDL is available.

Universal wheels (as in #91) would be preferred, but this is not strictly necessary.
