Even though they are actually not used directly and instead a step between the
PO file and generating the .js file

Trying to make it simpler and easier for people to add new translations by
reducing the amount of places where edits need to be made (e.g. no new edits
required in converse.js now).

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.
