#36 Canceling adding an item to desktop doesn't remove item

[FWishbringer]

If the user attempts to add an item (link or image) to the sharp desktop, and decide not to create an item and instead close the options dialog before setting anything, the item remains on the desktop. It would be more user intuitive to remove the item (link or image) if it is not altered in any way when the close button is selected, as neither produces a 'working' item if not set up.

Note: The recycle bin actually places a 'usable' item on the desktop, so would not need removed.
