Enable python -m pip-chill

[ckartchner]

Hi Ricardo. Thanks for your work on this project! It has helped me clean-up some of the sprawling dependencies in a few of the web applications I work on. :+1:

As an attempt to give back, I've tried to address issue #30 (pip-chill not executable as a package) with this PR

For packages that use no special characters, adding a __main__.py to the package directory is enough to enable python -m <package_name>, however, in this case, since the package is in the directory pip_chill (and pip-chill is an invalid module name), this only enables python -m pip_chill and not python -m pip-chill.

The work around in this PR is to both add a pip-chill.py to the top level directory which behaves identically to the __main__.py, and add this file to the py_modules section of setup.py

With these changes, python -m pip-chill, python -m pip_chill and pip-chill are all valid ways to execute the program.

The inspiration for this change came from the solution pip-run is using.

As an aside, maybe consider increasing the amount of time it takes for an issue to auto-close as stale, or remove auto-closing all together? I started looking at this issue last weekend, but didn't comment as I was merely exploring and didn't want to make any commitments. I was surprised to find the issue closed when I came back to create my PR today. It looks like this isn't the first potentially useful enhancement that auto-closer has moved to the closed pile.
