Add button for owned itemsSuggestion

I would like to be able to teleport, by using the builtin command `teleport2owneditem <ID> <Item (Optional)>`, from the ID in player administration instead of having to type it out in the console. Preferably the window would just stay open as you continually click it to cycle through items, or it would open an additional window with this functionality and a text box for the optional item. 

I'm still interested in this.
