    This function queries mods that can spawn on an item. It compares 
    the item tags and the spawn weight tags. If there's a match and 
    the spawn weight is larger than zero, then that mod is added to a 
    drop down list.
    
    To Do:
    * Add support to:
        * Forsaken masters
        * Bestiary
    * Add a proper expand/collapse toggle for the entire header row so 
        it reacts together with mw-collapsible. 
    * Show Mod group in a better way perhaps: 
        Mod group [Collapsible, default=Expanded]
            # to Damage [Collapsible, default=Collapsed]
                3 to Damage
                5 to Damage
    * Add a where condition that somehow filters out mods that obviously 
      wont match with the item. spawn_weights.weight>0 isn't enough due 
      to possible edge cases.
