feat(mafia): Deprecate Funsmith/Farmer/Tinkering modifiers, combine into single modifier (Name TBD)

[Golbolco]

• New modifier, name TBD
• Handled as an item (name examples: Storefront, Warehouse, Vault, Safe etc)
• On N1, use the Safe to pick an item and stock the safe with: options include gun, knife, bread, bomb, armor, syringe, falcon, candle, key, envelope, whiskey, tract, crystal ball
• Anyone who visits a player with this modifier will receive the item chosen
• If this player is killed, one of the killers will receive an always-revealing gun
• Deprecate Funsmith, Farmer, and the existing Tinkering modifier

• Remove Trickster role
• MAYBE: Add modifier that curses half of all items given out

This whole thing could expand out into an eventual item-giver overhaul similar to the ongoing Investigative overhaul, if we are ballsy/bored/masochistic. If that is the case, it should go hand-in-hand with #1512 and #1630

I feel like Setup creators should more control over what items can be given out as Guns and Syringes would always be chosen over falcons and Candles. I would propose 1 modifier for each item.

[Golbolco]

1 modifier for each item would be more of the same problem, but I agree we need to give setup creators better control. This will have to go on the backburner until we figure out how.
