fix one error in gunicorn_paster, global conf was ignored... While I'm

here change a little the behaviour of debug mode so we can still have
multiple workers in gunicorn :

- Don't preload app
- Set wsgi.multiprocess=False

rationnal is that when app isn't loaded it run in its own thread and
can't be evaluated by another process simultaneously. So setting
wsgi.multiprocess in this case sound good.
