[PR] Removes HoS whitelist requirement from halloween critters + nerfs them

[Zafhset]

I'm against these nerfs solely because it's possible to become remy/bumblespider/crows through other means (such as admins or wizard spells).

Don't dampen the overall experience/capabilities of those critters just to make them available for Spooktober. They are rare enough as is outside of this month.
