HyperConomy economies have their own accounts. Support them with special vaults.

According to the HyperConomy dev, it isn't the shop which has an account but the economy itself. HyperConomy supports multiple economies and each has an account. So we'd need an economy vault, not necessarily one per shop.

Okay, thanks for the clarification. I'll have to figure out anyway once I get to this :)
