Fixed some linting issues.
Changed portuguese translation path and fixed some strings

As exists basically Portugal portuguese and Brazil portuguese there
are some differences. The path to translation was changed from 'por' to 'pt_BR'
and some strings are now with a "brazilian" feeling. The way it was is very
formal and escapes from brazilian reality.
