Got rid of AppConfig._stub. As a side effect, app_cache.app_configs now only contains entries for applications that are in INSTALLED_APPS, which is a good thing and will allow dramatic simplifications (which I will perform in the next commit). That required adjusting all methods that iterate on app_configs without checking the "installed" flag, hence the large changes in get_model[s]. Introduced AppCache.all_models to store models: - while the app cache is being populated and a suitable app config object to register models isn't available yet; - for applications that aren't in INSTALLED_APPS since they don't have an app config any longer. Replaced get_model(seed_cache=False) by registered_model() which can be kept simple and safe to call at any time, and removed the seed_cache argument to get_model[s]. There's no replacement for that private API. Allowed non-master app caches to go through populate() as it is now safe to do so. They were introduced in 1.7 so backwards compatibility isn't a concern as long as the migrations framework keeps working.
