pip packaging

Not sure how you want to do the version numbering, so I just set it at 0.1 for now. I saw you had some tags but didn't look like they were still being used. Should definitely submit this to PyPi (https://pypi.python.org/pypi) so users can install from there.  

Can test install by running 
`pip install git+git://github.com/jlintz/phue.git@pip_package#egg=phue`
