Translation fix for portuguese

Hey Jesse,

this is Ana's friend from Awesome Rio. I fixed the problem on the portuguese translations for the submit project page. I also created a new translation for the "apply" button, both in portuguese and english since the caption was not translated.

The original pt.yml file was using CRLF instead of just LF, ergo the huge number of deletions.

If you see something that's not ok, let me know.

Tks!
