The shipping bin is accessible through Chests Anywhere, but it's categorised under "Farm" and players can't change that. Add support for editing the shipping bin info.

The category is normally stored in the chest.name field, which isn't possible for the shipping bin since there's no chest instance (it's just a List<Item>). There's an upcoming SMAPI API that will let mods store data in the save file (Pathoschild/SMAPI#468), which would be perfect for this.

Done in develop for the upcoming Chests Anywhere 1.14.
