Set the global level via the configuration object passed to log4js.configure or target all in the levels object.
Set the global level via the configuration object passed to
log4js.configure or target `all` in the `levels` object.
Changed to only the ‚levels’ option as discussed in #87

Add unit test to check if the level is set on all categories
