 * Introduction
 * ============================================================================
 *
 * This plugin alters various aspects regarding equipment handling. The changes
 * are as listed:
 *
 * 1. Scene_Equip
 * Scene_Equip has been modified to look differently. This is primarily done to
 * make the main menu scenes look uniform and keep everything familiar for
 * players. Furthermore, the command window has been adjusted to be better fit
 * for extension plugins in the future that may add commands to the command
 * window and/or the scene.
 *
 * 2. Equipment Type Handling
 * Characters will no longer have one universal equipment slot setting. Now,
 * different classes can use different setups by simply adding a few notetags
 * to the class notebox. Furthermore, equipment types in the past with matching
 * names would be treated as separate types. Now, equipment types with matching
 * names will be treated as the same type.
 *
 * 3. Equipment Rulings
 * Now, certain equipment types can or cannot be removed. For example, this
 * plugin can set it so that the Weapon slot must always have something
 * equipped and that the player cannot manually leave it empty (the game, on
 * the other hand, can achieve this through events). In addition to that,
 * optimizing equipment can be restricted for certain equipment types, which
 * are better off being decided manually (such as accessories).
 *
 * 4. Parameter Control
 * Equipment parameters can now to be adjusted through notetags to have a large
 * value or customized value (through code). This allows for equipment to no
 * longer be static items, but instead, equipment can now be dynamic and may
 * change over the course of the game.
 *
 * 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
 * ============================================================================
 *
 * You can use the following notetags to change a class's equipment setup.
 *
 * 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
 *   database's Types tab and look for the ID type.
 *
 *   If you don't like the above method for setting equipment slots, you can
 *   use the following notetags instead:
 *
 *   <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
 *   the same as the previous notetag.
 *
 * Weapon and Armor Notetags:
 *   <stat: +x>
 *   <stat: -x>
 *   Allows the piece of weapon or armor to gain or lose x amount of stat.
 *   Replace "stat" with "hp", "mp", "atk", "def", "mat", "mdf", "agi", or
 *   "luk" to alter that specific stat. This allows the piece of equipment
 *   to go past the editor's default limitation so long as the maximum value
 *   allows for it. Changes made here alter the base parameters.
 *
 * ============================================================================
 * 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.
 *
 * ============================================================================
 * Changelog
 * ============================================================================
 *
 * Version 1.17:
 * - Updated for RPG Maker MV version 1.5.0.

 * - Lunatic Mode fail safes added.
 *
 * Version 1.15:
 * - Optimization update.
 *
 * Version 1.14:

 *
 * 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:

 *
 * 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

 *
 * Version 1.08:
 * - Fixed a bug where changing an actor's equips would revive them if dead.
 *
 * Version 1.07:
 * - Fixed a bug with 'Optimize' and 'Remove All' not refreshing windows.
 *
 * Version 1.06:
 * - Fixed a bug with 'Change Equipment' event where it would only change the

 *
 * Version 1.05:
 * - Fixed an issue where unequipping items can kill actors.
 *
 * Version 1.04a:
 * - Fixed a bug and rewrote the initializing equipment process.
 *
