Update version numbers to end in ".1"; remove URLs

This is necessary for recent versions of pip to consider these packages
production instead of beta, and thus be willing to install them.  Also,
this patch removes all old URL fields since we will now need to upload
these packages directly to PyPI, since PyPI by default no longer pulls
packages from 3rd party locations.

Also, this removes all detritus that was left over in the setup.py files
from the era back when I just had a single combined setup.py that was
shared by all of the packages.
