* Use a single charge from a single item.

* For simplicity, you cannot use a stack of items from the
* ground.  This would require too much nasty code.
* There are no wands which can "destroy" themselves, in the inventory
* or on the ground, so we can ignore this possibility.  Note that this
* required giving "wand of wonder" the ability to ignore destruction
* by electric balls.
* All wands can be "cancelled" at the "Direction?" prompt for free.
* Note that the basic "bolt" wands do slightly less damage than the
* basic "bolt" rods, but the basic "ball" wands do the same damage
* as the basic "ball" rods.
