DuelJack

### v1.3.0
- DuelJack now speaks your game's language automatically: English, Spanish, Chinese and Portuguese. No setup needed; any other client language shows English.
- Everything is translated: windows, buttons, tooltips, chat messages, How to play, FAQ, options and keybinding names.
- The addon description in the AddOns list also appears in your language.
- Duel history dates use the day/month order of your language.
- Group chat announcements are written in the language of the player who posts them.
- New FAQ entry about supported languages, and Portuguese aliases for a few slash commands (`parar`, `desistir`, `placar`, `compartilhar`).
- Players using different languages can duel each other, and 1.3.0 still plays with every earlier version.
