translating to pt_BR - missions 62% done - engine 34% done (second try)

I don't made a git rebase because I just erased my FredMaranhao/PLM fork from github. I recreated it and overwrite the three files from my backup:
l10n/engine/pt_BR.po
l10n/missions/pt_BR.po
src/plm/universe/bugglequest/AbstractBuggle.java
