Feature Request: Portuguese Brazilian translation

### Translations, locales and i18n Add a translation using Poedit, gettext and intltool, like [Polychromatic](https://github.com/polychromatic/polychromatic) does, which is in python too. It has some scripts to do the job, so it take's the strings and merge in a .pot file, just have to mark them in the code. I can help to translate on portuguese Brazilian and to implement in the project. Haven't tried yet, but doesn't seems difficult. Wait for your repply.
