Convert hyphens in project_name to underscores in pkg_name

Would hyphens in the project name be a safe change? @mcdonc @tseaver

Two things:

• Should we be using some API from setuptools for matching / generating package name from project name?
• Either way, we need a test showing that the conversion works.

@tseaver, I added a test to make sure that hyphens in the project name are properly converted into underscores in the package name.

I looked at setuptools and found setuptools.dist.check_packages(), which validates package names using the regular expression \w+(\.\w+)*. However, that regular expression permits hyphens in the middle of the package name, which doesn't help. Interestingly, I found it is possible to import invalid package names using __import__('invalid-package-name'). For these reasons, I decided not to use functions from setuptools to generate the package name.

Thanks for backing out the extraneous changes via c1ef71c. This change looks good to me.
