Portuguese wrong translations (pt, pt-br) for month and day names.

Hi! I’ve trying to join the Portuguese translation team but maybe it is not required and somebody can fix them.
Month names (janeiro - dezembro) and day names (segunda-feira - domingo) should not be capitalized.
When we use them in date filter with DATE_FORMAT or DATETIME_FORMAT we get wrong date representations like:
25 de Outubro de 2006
that should be:
25 de outubro de 2006
