Token challenges are back

Token and TokenV2 are now available again. The pin/token algorithm hasn't been changed!

Token challenges broken

As it turned out, there were some additional (unintended) bugs in Token and TokenV2 which made them solvable far more easily than intended. We took them down for repair and will republish them with new flags.
