Make sure translations are ok

[drmowinckels]

We currently have 4 languages on the website, French (fr), Portuguese (pt), and Spanish (es), in addition to English.

The various translated strings around the webpage are defined in the themes-folder.
The strings need to be checked for good translations (they are now a mix of content I've found elsewhere and google translate, so I'm not expecting them to be awesome).

Anyone willing and able to help make sure the translations are good would be great.
