Add more subtitles to the Howto videos in Youtube

Last year we did some howto videos:

• How to use Tor Browser
• Unlock the Web with Tor Bridges! [Bypassing Censorship with Tor]
• Share Files Securely with OnionShare

We have posted version in Arabic, Swahili and Chinese, but we have some more subtitles to add:

• How to use Tor Browser : ca, de, el, es, fa, fi, fr, ga, it, ja, ko, pl, pt_BR, ru, sq, ta, tk, uk, vi
