Additional Facebook attestation metadata

[nick]

'Has Facebook' isn't terribly useful, perhaps we can also gather how many friends a user has as well as how old their account is. No need to be too specific... something like "More than 200 friends" and "Account is more than 5 years old"

@nick has also suggested adding more detail to all of the verification badges, such as including counts like we do in Chai.
