 * Introduction
 * ============================================================================
 *
 * 装备核心插件改变了游戏很多选项。将会影响装备菜单，装备类型索引，
 * 装备规则等等。
 * 
 * 插件改变包括如下：
 *
 * 1. Scene_Equip
 * 装备界面：装备界面调整了一下，会略微不同。主要是制作了主菜单让人
 * 看起来统一并且对于玩家更加熟悉。更长远来说，命令菜单可以更好的
 * 适应未来的拓展插件，以便添加命令
 *
 * 2. Equipment Type Handling
 * 装备类型：玩家不只有一个通用的设置。现在，不用的职业可以通过
 * 简单的标签来添加不同的设置。还有，之前名字一样的装备类型视为
 * 不同的类型，现在，名义一样的装备类型归为一类
 *
 * 3. Equipment Rulings
 * 装备规则：现在，装备类型可以被选择能不能移除。
 * 例如，这个插件设置了了武器必须装备，所以玩家武器栏不可以为空。
 * 除此之外，可选择装备被确定类型限制，最好关闭自动决定。
 *
 * 4. Parameter Control
 * 参数控制：装备参数可以同标签设置，来自设置一个较大的值或者自定义值。
 * 这将允许装备不再是静态物品而是可以通过游戏改变的
 *
 * Note: Item Core Users
 * For users using the Item Core plugin and the new Item Scene layout option,
 * the Item Info Window is now added to the Equip Scene. Pressing Left/Right
 * will toggle the stat comparison window with the info window. Pressing Tab on
 * the keyboard will also switch them as well as clicking on those windows.
 *
 * ============================================================================
 * Notetags
 * ============================================================================
 *
 * 你可以用下面的标签改变职业装备设置
 *
 * Class Notetags:
 *   <Equip Slot: x>      Example: <Equip Slot: 1, 2, 3, 4, 5, 5, 5, 5>
 *   <Equip Slot: x, x, x>
 *   Changes this class's equipment slots to x. Using repeating numbers makes
 *   it so that equipment type is duplicated and that the class can equip
 *   multiple equipment of that type. To find the Equipment Type ID, go to your
 *   例如：改变角色可以装备的类型ID
 *
 *   如果你不喜欢这个方法，你可以用下面方法替代:
 *
 *   <Equip Slot>         Example: <Equip Slot>
 *    string                        Weapon
 *    string                        Armor
 *    string                        Accessory
 *    string                        Accessory
 *   </Equip Slot>                 </Equip Slot>
 *   Replace 'string' with the Equipment type's name entry. This is case
 *   sensitive so if the string does not match a name entry perfectly, the slot
 *   will not be granted to the class. Multiple copies of a name entry would
 *   mean the class can equip multiple equipment of that type. Everything works
 *   用特定的物品类型放入代码即可。
 *
 * Weapon and Armor Notetags:
 *   <stat: +x>
 *   <stat: -x>
 *   允许武器装备或者或者失去某些值。你可以用血量、魔法值、攻击力
 *   、防御力、魔法攻击力、魔法防御力、速度或者幸运值来代替。
 *   这将允许装备可以突破默认编辑器的限制。
 *
 * ============================================================================
 * Lunatic Mode - Custom Parameters
 * ============================================================================
 *
 *   <Custom Parameters>  Example: <Custom Parameters>
 *    code                          atk = $gameVariables.value(1);
 *    code                          mat = atk / 2;
 *    code                          all = $gameParty.members().length;
 *    code                         </Custom Parameters>
 *   </Code Parameters>
 *   Allows for parameters to have custom rates adjusted by code. The following
 *   parameters are defined: 'maxhp', 'maxmp', 'atk', 'def', 'mat', 'mdf',
 *   'agi', 'luk', and 'all'. The 'all' parameter will affect all parameters.
 *   Changes made here do not alter the base parameters, but instead, are added
 *   onto the base parameters.允许玩家自定义参数。
 *
 * ============================================================================
 * Changelog
 * ============================================================================
 *
 * Version 1.16:
 * - Lunatic Mode fail safes added.
 *
 * Version 1.15:
 * - Optimization update.
 *
 * Version 1.14:
 * - Added an actor refresh upon listing the various equip slots to ensure that
 * all slots are updated in case any cache'd instances may have been missed.
 *
 * Version 1.13:
 * - Fixed a bug that caused a crash for those who weren't using the Item Core
 * in addition to this plugin.
 *
 * Version 1.12:
 * - Added optional functionality. Leaving 'Finish Command' empty will remove
 * it from being added to the command list.
 *
 * Version 1.11:

 * - Fixed a bug that did not clear changes made to an actor's stats after
 * having unequipped them and then switching actors.
 *
 * Version 1.09:
 * - For users using the Item Core plugin and the new Item Scene layout option,
 * the Item Info Window is now added to the Equip Scene. Pressing Left/Right
 * will toggle the stat comparison window with the info window. Pressing Tab on
 * the keyboard will also switch them as well as clicking on those windows.
 *
 * Version 1.08:
 * - Fixed a bug where changing an actor's equips would revive them if dead.
