- Supported languages now all centralized.

Now the flow for adding a new language is just:
1.Add a new language entry to `res/common/lang/langs.json`.

And for translating it's just:
1. Run `gulp translate` (extracts all the strings).
2. Open `/res/common/lang/po/stf.pot` in PoEdit and translate.
3. Run `gulp translate` again (creates a json based on the new `po` file).
