 * Help determine an "enchantment bonus" for an object.
 *
 * To avoid floating point but still provide a smooth distribution of bonuses,
 * we simply round the results of division in such a way as to "average" the
 * correct floating point value.
 *
 * This function has been changed.  It uses "randnor()" to choose values from
 * a normal distribution, whose mean moves from zero towards the max as the
 * level increases, and whose standard deviation is equal to 1/4 of the max,
 * and whose values are forced to lie between zero and the max, inclusive.
 *
 * Since the "level" rarely passes 100 before Morgoth is dead, it is very
 * rare to get the "full" enchantment on an object, even a deep levels.

 *
 * In particular, note that "Instant Artifacts", if "created" by an external
 * routine, must pass through this function to complete the actual creation.
 *
 * The base "chance" of the item being "good" increases with the "level"
 * parameter, which is usually derived from the dungeon level, being equal
 * to the level plus 10, up to a maximum of 75.  If "good" is true, then
 * the object is guaranteed to be "good".  If an object is "good", then
 * the chance that the object will be "great" (ego-item or artifact), also
 * increases with the "level", being equal to half the level, plus 5, up to
 * a maximum of 20.  If "great" is true, then the object is guaranteed to be
 * "great".  At dungeon level 65 and below, 15/100 objects are "great".
 *
 * If the object is not "good", there is a chance it will be "cursed", and
 * if it is "cursed", there is a chance it will be "broken".  These chances
 * are related to the "good" / "great" chances above.
 *
 * Otherwise "normal" rings and amulets will be "good" half the time and
 * "cursed" half the time, unless the ring/amulet is always good or cursed.
 *
 * If "okay" is true, and the object is going to be "great", then there is
 * a chance that an artifact will be created.  This is true even if both the
 * "good" and "great" arguments are false.  As a total hack, if "great" is
 * true, then the item gets 3 extra "attempts" to become an artifact.
