Laid foundation for localization function...

Added translations for “Download the Tor Browser”, if anyone has a
better translation for any of these please fix…
also please help translate the rest of the phrases..

The function will be called anytime the language is changed and when
the language is set… using jQuery it will **hopefully** change all the
text on the page to the correct language.
