setup: Install outrules.d

This plugs outrules.d into setup.py's data_files.  It also tidies up
several loose ends in setup.py, converting the versioning scheme to
conform with what is purported to be the standard pythonic scheme,
adding a long_description, fixing the dummy url, specifying the license
(redundantly), and adding a maintainer.

This way, when installed via Gentoo distutils-r1, the outrules.d files
wind up in ${EPREFIX}/usr/share/overlay-upstream-tracking/outrules.d.

(now if only I can figure out a way to access this file location without
hard-coding it somewhere... perhaps this is the ticket?:
