Miscellaneous: Ant's Potion shouldn't be craftable until Feb 2000 alchemy revamp

[Dolalin]

People can still make 1 and 10 dose ant potions apparently.

I guess with shrink coming out in two weeks this isn't super urgent but should be fixed for the next server. It elevates the Guise to the essential status it had in classic for big races as the only shrink option.

Also note that shrink pots didn't work outdoors until after Kunark release, I mentioned this somewhere already I'm pretty sure, it's in the patch notes.
