email addresses check fail on travis, but i want to keep the content synced with tox.chat

[zugz]

What's the reasoning behind this PR? Why do we want to move these pages to toktok, and is tox.chat happy with the change?

[zoff99]

@zugz we discussed this a while ago with @iphydf the about page needs some tweaks, not all info is still correct. i am just copying both pages as-is. we can talk about linking later.

[zugz]

The new versions of the pages look fine to me, in that nothing important has changed from the originals, except for the missing question marks in the questions, and a missing colon. I think they should be put back (even if this means rule changes).

[zoff99]

@iphydf do you want to relax the rules for headers or want me to leave it like this ("?" and ":" removed from ending of headers) ?

+However, a non-friend user cannot easily +discover your IP address using only a Tox ID; you reveal your IP address

This sentence seems to be wrong now.

With "easily", I think it's ok. I'd support including a link to #1152, though.

+## What is stopping people from tracking me through the public DHT

Is this section accurate? @zugz

Again, it's technically accurate, as it only claims to make things "more difficult" for an attacker. But again, linking to #1152 would make sense.

@zugz what should be the text linking to https://github.com/TokTok/c-toxcore/issues/1152 ? can you word something?

Probably best to leave this to a separate PR, once we're sure where the FAQ will live? I can draft something then.
