Add symlinking for setup.py-defined scripts and entry_points['console_scripts']

[monopolis]

This patch adds a <package>.links file to the debian folder, to set up
symlinks for scripts and entry_points described in setup.py. In addition,
it alters the method for parsing setup.py to be based on distutils
(setuptools is required to support the entry_points['console_scripts]-parsing).

I get an error with this PR:

Nevermind, it was an issue with my setup.py format. I can confirm this patch works.
