* Extended how duplicates work: (based on Orcao's work in bugreport:2361) [FlavioJS]

- you can duplicate warps/shops/cashshops/npcs (before only npcs could be duplicated)
- warp duplicates inherit the target location
- shop/cashshop duplicates inherit the item list
- npc duplicates inherit the script code (backward compatible behaviour)
- updated script_commands.txt with the information
