 * Introduction
 * ============================================================================
 *
 * Item synthesis is now a pretty common aspect of most RPG's where the player
 * can craft their own items after acquiring recipes. This plugin enables your
 * players to be able to do that after acquiring the said recipes. Recipes can
 * come in the form of items, weapons, and/or armors and transcribed in them
 * are what items, weapons, and/or armors they can make. These items can be
 * made from the main menu and/or synthesis locations!
 *
 * ============================================================================
 * Notetags
 * ============================================================================
 *
 * To allow the player the ability to craft a certain item, that item must be
 * included in a recipe notetag in an item that the player possesses.
 *
 * Item, Weapon, and Armor Notetags:
 *   <Item Recipe: x>
 *   <Item Recipe: x, x, x>
 *   <Item Recipe: x to y>
 *   This will change this item into a recipe for x item(s). As long as this
 *   item is in possession by the party as a whole, item(s) x can be
 *   synthesized by the player provided that the player has the proper quantity
 *   of ingredients.
 *   * Note: Entries without names will not be included. Entries without both a
 *   synthesis cost and without an ingredient list will not be included.
 *
 *   <Weapon Recipe: x>
 *   <Weapon Recipe: x, x, x>
 *   <Weapon Recipe: x to y>
 *   This will change this item into a recipe for x weapon(s). As long as this
 *   item is in possession by the party as a whole, weapon(s) x can be
 *   synthesized by the player provided that the player has the proper quantity
 *   of ingredients.
 *   * Note: Entries without names will not be included. Entries without both a
 *   synthesis cost and without an ingredient list will not be included.
 *
 *   <Armor Recipe: x>
 *   <Armor Recipe: x, x, x>
 *   <Armor Recipe: x to y>
 *   This will change this item into a recipe for x armor(s). As long as this
 *   item is in possession by the party as a whole, armor(s) x can be
 *   synthesized by the player provided that the player has the proper quantity
 *   of ingredients.
 *   * Note: Entries without names will not be included. Entries without both a
 *   synthesis cost and without an ingredient list will not be included.
 *
 *   <Synthesis Ingredients>
 *     item id
 *     item id: x
 *     weapon id
 *     weapon id: x
 *     armor id
 *     armor id: x
 *     gold: x
 *     named item
 *     named item: x
 *   </Synthesis Ingredients>
 *   Using the above tag in an item will set those items as the ingredients
 *   required for the player to synthesize. Replace "id" with the proper item,
 *   weapon, or armor ID's. If no ":x" is used, the database will register that
 *   as only needing 1 of that item as an ingredient. If "gold: x" is used,
 *   that will be the cost required to synthesize the item.
 *
 *   If you are using named entries, priority will be given to the highest ID
 *   in the order of items, weapons, then armors.
 *
 *   * Note: If you are using Item Core, Independent Items cannot become an
 *   ingredient for a recipe and will therefore be automatically omitted.
 *
 *   <Mask Name: x>
 *   If you are masking unknown items' names, you can change the text shown for
 *   the unknown item with x. This will cause the game to use the mask name
 *   instead of the usual ??? (if that's what you're using) to mask the item.
 *   This can give a player a general idea of what they may be synthesizing
 *   such as "Strange Liquid" or "Weird Crystal".
 *
 * ============================================================================
 * Lunatic Mode - Custom Synthesis Effects
 * ============================================================================
 *
 * For those with a JavaScript experience, you can use these notetags to make
 * a custom effect that will occur when a specific item is synthesized. For
 * example, when a Potion is made, you can give the player an empty bottle as a
 * side product of the synthesis.
 *
 * ---
 *
 * Item, Weapon, and Armor Notetags:
 * 
 *   <Custom Synthesis Effect>
 *    var bottle = $dataItems[123];
 *    $gameParty.gainItem(bottle, 2);
 *   </Custom Synthesis Effect>
 *
 *   For this notetag, the 'item' variable will refer to the item being
 *   synthesized. Changing it will do nothing but it will be used as a
 *   convenience variable to refer to it.
 *
 * ---
 *
 * ============================================================================
 * Plugin Commands
 * ============================================================================
 *
 * The following are Plugin Commands you may use with events.
 *
 * Plugin Command:
 *   OpenSynthesis          Opens up the Synthesis Scene from the field.
 *   ShowSynthesis          Shows the Synthesis command from the main menu.
 *   HideSynthesis          Hides the Synthesis command from the main menu.
 *   EnableSynthesis        Enables the Synthesis command from the main menu.
 *   DisableSynthesis       Disables the Synthesis command from the main menu.
 *
 * For those who wish to make the player synthesize only specific recipes, you
 * can use the following command.
 *
 *   OpenSynthesis Item 15 Recipe
 *   - or -
 *   OpenSynthesis Weapon 20 Recipe
 *   - or -
 *   OpenSynthesis Armor 30 Recipe
 *
 * This will make the synthesis menu, when opened up, only allow the recipes of
 * the Item 15, Weapon 20, or Armor 30 without needing it and not showing the
 * recipes of any recipe items within the player's inventory.
 *
 * ============================================================================
 * Changelog
 * ============================================================================
 *
 * Version 1.11:
 * - Bypass the isDevToolsOpen() error when bad code is inserted into a script
 * call or custom Lunatic Mode code segment due to updating to MV 1.6.1.
 *
 * Version 1.10:
 * - Added 'Amount Format' plugin parameter. Now you can switch the way the
 * needed ingredients are shown between Need/Own and Own/Need.
 *
 * Version 1.09:
 * - Updated for RPG Maker MV version 1.5.0.
 *
 * Version 1.08:
 * - Lunatic Mode fail safes added.
 *
 * Version 1.07:
 * - Added <Custom Synthesis Effect> Lunatic Mode notetag.
 *
 * Version 1.06:
 * - Fixed an error with the calculation of total recipes.
 *
 * Version 1.05:
 * - Updated for RPG Maker MV version 1.1.0.
 *
 * Version 1.04:
 * - Added failsafes to prevent crashes from saved games that did not have this
 * plugin already installed.
 *
 * Version 1.03a:
 * - Fixed a bug that caused a crash for OpenSynthesis recipe commands.
 * - Fixed an issue with recipe counts not appearing right.
 *
 * Version 1.02:
 * - Added 'Equipped Recipes' plugin parameter. If enabled, this will allow the
 * Item Synthesis menu to check your party's equipment to see if any of them
 * are recipe holders.
 *
 * Version 1.01:
 * - Fixed a bug with the synthesis gold costs taking more than they should.
 * - Extended the OpenSynthesis plugin command. If you add Item, Weapon, or
 * Armor after the command along with an ID, the synthesis menu will only show
 * the items listed on the recipe for Item x, Weapon x, or Armor x.
 *
 * Version 1.00:
 * - Finished Plugin!
