Title: PT-BR Translation

PT-BR Translation. Not sure if I should call it pt.php or br.php (to differentiate it from Portuguese (Portugal)). I'll leave that to you.
Also, I didn't find where olclang["err"] is printed so I can check that the translation is 100% accurate, but it appears to be correct from the original English string.
