Add support for ender Expansion

[rourke750]

Currently the inventory is one created through bukkit.creatinventory so interacting with an inventory like ender chests its going to get the wrong one.
So I dont think that ender expansion will work with item exchange because of how ender expansion finds the inventory. Can you add somewhere if the player interacts with a ender chest then to find the inventory you need to use this line of code :

Location loc = e.getClickedBlock().getLocation();
Inventory inv = Enderplugin.getchestInventory(loc);

using that code and by placing the location of where the ender chest is you can find the correct inventory.
