Portuguese translation can't be downloaded automatically when chosen.
Portuguese translated .lang file is available, can be manually downloaded
and tested using another idiom as alias.
It's attached a proposal for Brazilian Portuguese (Brazil) translation
for BowPad 2.3.5. Like Portuguese translation, UTF-8 enconding was used,
but It's enclosed a similar file encoded with ISO8859-1.
