OverrideItemImage_Improved
Tracking Issue: #962
The OverrideItemImage_Improved X2DLCInfo method is called from XComGameState_Item::GetWeaponPanelImages().
It allows mods to conditionally override item's inventory image.
It can be used to replace the original image entirely
or to overlay an additional icon on top of it to mark the specific item.
To do so replace the contents of the imagePath array or add more image paths to it.
