Brazilian Portuguese built-in deck and translation update

[flipeip]

Here is the translation to the new strings and the built-in deck (following #127).
Also, I want to note that the deck's name is actually the translation of "Cards Against Humanity" in this language, but I'm not sure if this is the right option.

Wow, thanks for such a quick PR!

As to the name, that's a good question.

Ideally we'd explicitly note the language and the fact this is a translation rather than a localization (at least, I assume—as far as I can tell it still includes American references and so on, and is a direct translation). For now, I think this is probably fine, and I'll probably take a look at some point at expanding the amount of detail about the decks we present.

Sorry this took me so long to pull in, but it now is in. Thanks again for the contribution!
