Adds easy language switch in admin
- add 'admin_langswitch' to INSTALLED_APPS (after putting it on PYTHON PATH)
- add '(r'^i18n/', include('django.conf.urls.i18n')),' to your urls.py
If you plan to use django-admin-langswitch with DjangoCMS (http://www.django-cms.org/), you should replace 'cms.middleware.multilingual.MultilingualURLMiddleware' with customised middleware. You can use 'admin_langswitch.middleware.CustomMultilingualURLMiddleware'. Please look into that module for a moment before you deploy. Of course in case you don't use DjangoCMS, this middleware is absolutely not needed.
