New Updates: For keeping doors open and for kingdom items

[Admins]

In the last few days we have added following:
- fixed a bug that crashed Graal Kingdoms (no crash since then)
- when you are inside your player house you can open the door and type /lockdooropen, then the door will stay open even if the server restarts or whatever, for closing it again just close it normally; this is good for player-ran shops
- we can now restict the use of certain items to single kingdoms or accounts, making it possible to add items which can only be applied by members of one kingdom (e.g. weapons or armour); those items cannot be traded via trade-tables or player-to-player trading
- modified the handling of messages (on the right side) so that the display is faster and is not producing an error from time to time
- when using player-to-player trading (drop an item on someone else) then the right-click-on-item is working again and is displaying the stats of the item, so that the buyer can verify that it is the good item

About existing 'kingdom' items: Those were not locked to a kingdom and we probably cannot punish the people who got them somehow, so the new kingdom-lock will probably be used only for new items.
