Update of pt-BR autocorr list.

Work is based on work according to author:
"   - 'DocumentList.xml'    - This is the second version, with the changes introduced in 5.2.1. The file is not a patch, so it should replace the former one. The diff file is on the bug page. It should credit the Brazilian team, since the changes are mostly from them. I mostly triaged and cherry-picked.
    - 'SentenceExceptList.xml'    - This is the abbreviations exception list. I have not done any work on it. Cherry-pick from the Brazilian version, so credit goes to them.
    - 'WordExceptList.xml'    - Two Caps Letters exceptions. I have not done any work on it. Cherry-pick from the Brazilian version, so credit goes to them."

Only DocumentList.xml contained changes.

Original was sent by mail.
