Add customization of default lang

Yes of course.

What about this:

	if (typeof window.CustomNECDefaultLanguage == 'undefined') {
    // window.CustomNECDefaultLanguage is not defined, set to defaults
    window.CustomNECDefaultLanguage = 
    "en";
	}
    var neccode = window.CustomNECDefaultLanguage; // this replaces line 21
