BuildingHelper:UpgradeBuilding

[SirWayN3]

I just found an error and some suggestions regarding this function.

Error: function BuildingHelper:BlockPSO(size, location) -- if size == 0 then return end -- size can be nil, when no KV "PathingSize" has been set if size == 0 or size == nil then return end

Suggestions:

1. Add Upgrade Duration to the Function
2. Add Modifier Copy & Paste from the old Building to the new.
3. Make new Building selected by Default
4. Remove Building Invulnerable from newly spawned Building

To 3: directly after local new_building = BuildingHelper:PlaceBuilding( -- Remove invulnerability on npc_dota_building baseclass new_building:RemoveModifierByName("modifier_invulnerable")
