Rotten Eggs Are Not Saltbox Valid

When regular eggs turn into rotten eggs in the Salt Box, they will spat out of the Salt Box, which differs from Spoiled Food, Spoiled Fish Morsel and Spoiled Fish Meat.

The conditionals in containers.lua for the saltbox:

function params.saltbox.itemtestfn(container, item, slot)
	return ((item:HasTag("fresh") or item:HasTag("stale") or item:HasTag("spoiled"))
		and item:HasTag("cookable")
		and not item:HasTag("deployable")
		and not item:HasTag("smallcreature")
		and item.replica.health == nil)
		or item:HasTag("saltbox_valid")
end

In rottenfn() function in egg.lua, the rotten eggs don't have the saltbox_valid tag.

local function rottenfn()
    local inst = CreateEntity()

    inst.entity:AddTransform()
    inst.entity:AddAnimState()
    inst.entity:AddNetwork()

    MakeInventoryPhysics(inst)

    inst.AnimState:SetBank("birdegg")
    inst.AnimState:SetBuild("bird_eggs")
    inst.AnimState:PlayAnimation("rotten")

    inst:AddTag("icebox_valid")
    inst:AddTag("cattoy")
  -- no inst:AddTag("saltbox_valid") to prevent rotten eggs from being spat out.
