Alexei Sorokin 024f5fe3a8 [RequireValidatedEmail] Only check current user posts
This check made registration impossible when welcomeuser didn't have validation
as well.

And rename the "grandfatherCutoff" option to "exemptBefore".
"Grandfathering" is a relatively obscure term linked to the history of the
United States of America, so replace that with something self-descriptive.
