Hack to overcome Python's bug 3136 in logging system (refs #7).

logging.config.fileConfig() disables all existing loggers that are not
configured using the config file. This hack re-enable the loggers so
everything works as expected even when you don't specify *all* the loggers
in the configuration files (and child loggers really inherits their parent
configuration).
