Save Items Rectangles
There can be areas in towns where items left there are remembered,
even after the party leaves town.
Enter the numbers of the towns where items are saved (-1 means no area),
and the rectangles where the items left are remembered.
if the party leaves the given town with an item on the ground inside the given rectangle,
the item will still be there when they get back.
If the item is not inside the rectangle, it is lost.
Note that the three towns must be different.
