Bukkit

- add optional return "portal" cloud for lingering potion (enabled by default), splash potion, StrangeBlock and StrangeRune

- add Right click a Strangebolock with a voodoo doll to link it to the entity, so you can use the strange block to teleport to entity after without using the voodoo Doll, right click again (the voodoo doll need to have the same entity linked) to remove the link and use the strange block like before, you have to be the owner of the strangeBlock...

- add message for targeted player when linked to a voodoo doll

- add conf options for customise return cloud (cloud duration, enabled Strange items)

- add admin command to duplicate item in hand (can be used to copy StrangeRune,Strange Potions, and more...) : /runescopy [amount]

- better version check

- fix items list preview in ChestRune Lore (when interact with other inventories)
