Add support for python packaging.

Added a setup.py for packaging. This will install the .py files as autospec
library in dist-packages. Because of the way the imports are currently done, autospec.py
is installed in dist-packages dir. The rpm packaging should create a symlink to this file at
/usr/bin/autospec.py
