[Tails-dev] Clarification of Tor enforcement on the website

As proposed in a bug report, I tried to clarify a little bit our Tor
enforcement on the "About" page with this commit:

http://git.tails.boum.org/tails/commit/?id=e0dba123f20e0df72ac723510b6fba093a1a29d7

I corrected that directly into master, but please have a look at it still.
