 * ============================================================================
 * 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.
 *
 * ============================================================================

 *
 * ===========================================================================
 * 導入
 * ===========================================================================
 *
 * このプラグインでは、装備のハンドリングに関するいくつかの要素を変更します。
 * 詳細は下記を参照してください:
 * 
 * 1. Scene_Equip
 * Scene_Equipは見た目の変更を行います。
 * 主にメインメニューの見た目を統一し、
 * プレイヤーにとって親しみやすいものへと変更します。
 * 今後リリースされる拡張プラグインに対応できるように、
 * コマンドウィンドウについても最適化されています。
 * 
 * 
 * 2. 装備タイプの扱い
 * 職業のメモ欄にメモタグを加えると、職業毎に異なる設定ができます。
 * 同じ名前を持った装備タイプは、単独としてバラバラに扱われていました。
 * このプラグインでは、同じタイプとして扱うことができます。
 * 
 * 3. 装備ルール
 * 特定の装備タイプは外すことができなくなります。
 * 例えば'武器は常に何かしら装備していなくてはならない'という設定が可能で、
 * プレイヤーは武器を勝手に外すことはできなくなります。
 * (イベントを通して解除させることもできます。)
 * それに加えて、特定の装備タイプを指定して、最強装備の制限もできます。
 * 装飾品のような装備タイプに関しては手動で決定させた方が良いでしょう。
 * 
 * 4. パラメータコントロール
 * メモタグを用いることで、装備パラメータに、
 * 大きな値やカスタマイズされた値を付与することができます。
 * (コードを通して実行されます)
 * 装備品は固定の性能を持ったアイテムではなくなり、
 * ゲームを通して性能が変動するようなものとなります。
 * 
 * 注: アイテムコア（Item Core）を使用してる方々
 * アイテムコアのプラグイン、Item Sceneレイアウトオプションを使っている方へ。
 * 「Item Info Window」は「Equip Scene」に移動されました。
 * 左・右キー、タブキー、それぞれのウィンドウをクリックすると
 * パラメータを比べるウィンドウと情報ウィンドウが表示されます。
 *
 * ===========================================================================
 * メモタグ
 * ===========================================================================
 *
 * 職業の装備設定を変更するには、下記のメモタグを用いてください。
 *
 * 職業のメモタグ:
 *   <Equip Slot: x>
 *   <Equip Slot: x, x, x>
 *
 *   例:
 *   <Equip Slot: 1, 2, 3, 4, 5, 5, 5, 5>
 *   職業の装備スロットを x に変更します。
 *   繰り返し同じ番号を使うことにより装備タイプを複製し、
 *   その職業は同タイプの装備を複数着けることができます。
 *   タイプIDは、データベースのタイプタブを確認してください。
 *
 *   上記の方法が気に入らない場合、下記のメモタグを代わりに用いてください。
 *
 *   <Equip Slot>
 *    string
 *    string
 *    string
 *    string
 *   </Equip Slot>
 *
 *   例:
 *   <Equip Slot>
 *    Weapon
 *    Armor
 *    Accessory
 *    Accessory
 *   </Equip Slot>
 *   'string'を装備タイプの名前に変えてください。
 *   正確な照合のため、名前が完全に合致しない場合、
 *   スロットは動作しません。
 *   複数コピーされた名前は、
 *   その職業がそのタイプの装備を複数着けることができます。
 *   全て、前述のメモタグと同様に動作します。
 *
 * 武器、防具のメモタグ:
 *   <stat: +x>
 *   <stat: -x>
 *   武器・防具で能力値を、 x だけ増加・減少させます。
 *   "stat"の部分を"hp", "mp", "atk", "def", "mat", "mdf", "agi", "luk"
 *   のような特定のステータスに変更してください。
 *   この機能は、デフォルトの最大値の上限を無視して使うことができます。
 *   ここで成された変更は、通常能力値を上書きします。
 *
 * ===========================================================================
 * ルナティックモード - カスタム能力値
 * ===========================================================================
 *
 *   <Custom Parameters>
 *    code
 *    code
 *    code
 *    code
 *   </Custom Parameters>
 *
 *   例:
 *   <Custom Parameters>
 *    atk = $gameVariables.value(1);
 *    mat = atk / 2;
 *    all = $gameParty.members().length;
 *   </Custom Parameters>
 *   パラメータに、コードによって適用されたレートを設定することができます。
 *   次のパラメータが定義されます:
 *   'maxhp', 'maxmp', 'atk', 'def', 'mat', 'mdf', 'agi', 'luk', and 'all'
 *   'all' のパラメータは、全てのパラメータに作用します。
 *   ここでの変更は通常能力値を上書きしませんが、追加保存されます。
