Initial commit for Portuguese translation.
Translation of the index page.
Updates in config and default layout to display properly Portuguese characters.
Attempt of Portuguese transaltion of "index" and "setup" page.

- Doesn't contain proper structure to support multilingual app so there is no support for navigation, switching the language, etc.

- Translated file names ".pt." and valid links in the content were updated (not navigation)

- No idea if some of the terms should be actually translated ex. "Syntax highlighting", "Auto-indent".
