adding error_reporting() as 2nd parameter (error_levels), when registering the errorhandler, results in not having to have a call to errorHandler() whenever PHP throwing an error, but only for those, that are activated. E_WARNINGs and E_NOTICEs can sum up very fast in hundreds to thousands of unnecessary calls to errorHandler(), just to have errorHandler() to decide not to throw an exception. Drawback of this version: if you change error_reporting after registerErrorHandler(), you have to call registerErrorHandler again, in order to get the new error_reporting into count. For backward compatibility, a new parameter ($use_error_reporting) is introduced, defaulting to false, providing the functions old behaviour
