Don't be mean to Tails plz (Pandora's Box Super cheat fix)

Removes the restriction on the Allow Super cheat preventing Tails from turning super. We have seen the error of our ways and removed this barbaric cruelty to foxes! :( More seriously though, this was just experimenting and we forgot to remove it for 2.2.

I was actually tempted to commit this fix straight to master but I've been persuaded not to. :)
