This is so that the code only gets parsed once initialized is called.

We want the code to be parsed only then, because this allows us to
specifiy the translation language as a configuration setting to initialize.

It will pull in all languages and put them in the locales root object, from
which the specific language translations can be chosen during runtime.

Also added js files with af and en translations.

Also a bugfix: make sure to render the status widget when the user doesn't have
any roster contacts.

When a user has been removed from a room and the room is still open,
we want to re-use that same room once they join it again.

As a result we now implement more status codes from the spec.
Specifically the codes related to forced removal form the room

Also fixed a bug related to wrong authentication when logging in.

To aid with dev

- list of rooms dropped off the controlbox
