Create a default logging config

paste uses paste.ini to configure python's logging module.

Until now, there was NO config, not even a useful default
one. This means: any messages went away unseen.
Not good.

The new default logs everything to stderr at level INFO and
higher. Maybe not the best, but a good starting point.
