 * This code adds a new spell, called alchemy.  Alchemy will turn
 * objects to gold nuggets, the value of the gold nuggets being
 * about 90% of that of the item itself.  It uses the value of the
 * object before charisma adjustments, because the nuggets themselves
 * will be will be adjusted by charisma when sold.
 *
 * Large nuggets are worth 25 gp each (base).  You will always get
 * the maximum number of large nuggets you could get.
 * Small nuggets are worth 1 gp each (base).  You will get from 0
 * to the max amount of small nuggets as you could get.
 *
 * For example, if an item is worth 110 gold, you will get
 * 4 large nuggets, and from 0-10 small nuggets.
 *
 * There is also a chance (1:30) that you will get nothing at all
 * for the object.  There is also a maximum weight that will be
 * alchemied.
