 * @plugindesc Changes how Luck is used by the engine
 * @author Ben Hendel-Doying
 *
 * @help With this plugin enabled, luck no longer effects item uses; instead,
 * it provides a bonus (or penalty) to the gold earned at the end of each combat.
 * Every point of luck ABOVE 100 gives +1% gold; every point BELOW 100 gives -1%.
 * For example, a party member with 90 luck means you get -10% gold. A party
 * member with 163 luck means you get +63% gold. These add together, so if you
 * had both of the above members in your party, you'd get +53% gold. Finally:
 * if you have the "double gold" skill in your party, it adds +100% gold, so if
 * you had both of the above members in your party, and any (or both) of them
 * had "double gold", you would get +153% gold from battles.
