It is now possible to define the log-handler in the config
file. It should be done in the same manner as the addons_path,
i.e. a comma-separated list of strings.
There is no need to pass the default :INFO handler, as this
will be automatically added by the system.
As an example, you can have:
log_handler = werkzeug:CRITICAL,openerp.netsvc.rpc.response:DEBUG
