loot:RemoveItem(itemid)
loot:GetMoney()
loot:SetMoney(amount)
loot:GenerateMoney(minMoney, maxMoney)
...

This'll need some changes or methods possibly removed to be compatible with the Mangos based cores. I'll see if I have the time to add the Mangos files to this PR this weekend.

I'm taking the liberty of closing this PR for the time being, as the Eluna structure is not up to date on this branch, so I'll have to update it manually.
