DoubleX RMMV Item Charge v100a

/*============================================================================
 *    ## Plugin Info
 *----------------------------------------------------------------------------
 *    # Plugin Name
 *      DoubleX RMMV Item Charge
 *----------------------------------------------------------------------------
 *    # Introduction
 *      Suppose a battler has n action slots(that battler can input n actions
 *      in a single turn), and suppose that battler has inputted n actions,
 *      each needing xi turns to be charged, where 1 <= i <= n, then that
 *      battler will behave as follows:
 *      1. At turn y, that battler has inputted the aforementioned n actions
 *      2. At turn y + x1, that battler will execute the 1st inputted action
 *      3. At turn y + x1 + x2, that battler will execute the 2nd inputted
 *         action
 *      4. At turn y + x1 + x2 + x3, that battler will execute the 3rd
 *         inputted action
 *      5. At turn y + x1 + x2 + x3 + ... + xi, where 1 <= i <= n, that
 *         battler will execute the ith action
 *      6. At turn y + x1 + x2 + x3 + ... + xn, that battler will execute the
 *         nth action
 *      7. At turn y + x1 + x2 + x3 + ... + xn + 1, that battler will become
 *         able to input actions again
 *      If the ith action that's not executed yet is the 1st one needing
 *      charging, the battler speed will only take the first (i - 1)th
 *      actions' speeds into account
 *      Item charging's ignored by forced actions

/*:
 * @plugindesc Lets you set skills/items to need turns to charge before using
 * @author DoubleX
 *
 * @param isEnabled
 * @desc Sets whether this plugin will be enabled
 *       It'll be stored as a boolean, and will be regarded as true if and only
 *       if it's true
 *       Don't change this during the same battle unless you really know what
 *       you're truly foing
 *       E.g.: Setting isEnabled as false will disable this plugin
 * @default true
 *
 * @param textColor
 * @desc Sets the text color of the text showing the number of turns needed to
 *       charge the skill/item on the skill/item window
 *       It'll be stored as a Number
 *       Don't change this when it's shown to ensure proper text displays
 *       E.g.: Setting textColor as 31 will set the text color of the text
 *             showing the number of turns needed to charge the skill/item on
 *             the skill/item window as 31
 * @default 30
 *
 * @help
 * The skill/item window charging turn display can be problematic if the
 * number of turn's 1000 or above
 * The default plugin file name is DoubleX RMMV Item Charge v100a
 * If you want to change that, you must edit the value of
 * DoubleX_RMMV.Item_Charge_File, which must be done via opening this plugin
 * js file directly
 *============================================================================
 *    ## Notetag Info
 *----------------------------------------------------------------------------
 *    # Skill/Item Notetags:
 *      1. <item charge: turns>
 *         - Sets the number of turns needed to charge the skill/item before
 *           using it as turns
 *         - E.g.:
 *           <item charge: 1> will set the number of turns needed to charge
 *           the skill/item before using it as 1
 *         - Only the 1st notetag will be used
 *============================================================================
 *    ## Plugin Call Info
 *----------------------------------------------------------------------------
 *    # Configuration manipulations
 *      1. $gameSystem.itemCharge.param
 *         - Returns the stored value of param listed in the plugin manager
 *         - E.g.:
 *           $gameSystem.itemCharge.textColor will return the stored value of
 *           parameter textColor shown on the plugin manager
 *      2. $gameSystem.itemCharge.param = val
 *         - Sets the stored value of param listed in plugin manager as val
 *         - E.g.:
 *           $gameSystem.itemCharge.isEnabled = false will set the stored
 *           value of parameter isEnabled shown on the plugin manager as false
 *         - All $gameSystem.itemCharge.param changes will be saved
 *    # Skill/Item notetag manipulations
 *      1. meta.itemCharge
 *         - Returns the <item charge: turns> notetag value turns as a Number
 *         - E.g.:
 *           $dataSkills[1].meta.itemCharge will return the
 *           <item charge: turns> notetag value of skill with id 1
 *      2. meta.itemCharge = turns
 *         - Sets the <item charge: turns> notetag value turns as a Number
 *         - E.g.:
 *           $dataItems[2].meta.itemCharge = 0 will set the
 *           <item charge: turns> notetag value of item with id 2 as 0
 *         - All meta.itemCharge changes can be saved if
 *           DoubleX RMMV Dynamic Data is used
