 * Help determine an "enchantment bonus" for an object.

 * To avoid floating point but still provide a smooth distribution of bonuses,

 * 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.
