Internationalise JavaScript code

Merged username-removed-124398 requested to merge NicoAlt/repomaker:109-internationalise-js into master

I did not find any way to let Django add the translations from JavaScript to "django" instead of "django.js".

This is the code I tried:

js_info_dict = {
    'domain': 'django',
    'packages': ('maker.apps.MakerConfig',),
}

urlpatterns = [
    # JavaScript Internationalisation
    url(r'^jsi18n/$', javascript_catalog, js_info_dict, name='javascript-catalog'),
