Fix i18n parse errors with locale files (en/pt)

While running bundle install on Rails 3.2.12, I was facing a strange error on i18n gem. 

On the `config/locales/en.yml` file, some lines were missing the `!` character ( I took the translation file from here: https://raw.github.com/svenfuchs/rails-i18n/master/rails/locale/en.yml 

On the `config/locales/pt.yml` the **line 472**, attribute `waiting_owner`, the character `\o/` was creating the following exception:

```bash

➜  /vagrant git:(master) ✗ rake db:migrate db:test:prepare --trace

can not load translations from /vagrant/config/locales/pt.yml, expected it to return a hash, but does not

I removed the char, and everything is OK. I think it's because it was escaping the `\o`, not sure tho.

Thanks!
