 * @help =============================================================================
 * • Introduction
 * =============================================================================
 *   YEP Item Core is NEEDED!
 * 
 *   This plugin is for upgrading actor's weapon with parameters growth formula.
 * 
 *   All text parameters support escape characters, just add double backslash
 *   before the code, for example \\I[25] \\C[4].
 * 
 * =============================================================================
 * • Weapon Notetags
 * =============================================================================
 *   <upgradeFormula TYPE: FORMULA>
 *   Set upgrade parameter growth formula.
 *   TYPE: mhp, mmp, atk, def, mat, mdf, agi, luk.
 *   FORMULA: a = actor, b = weapon, c = level.
 *            To get the weapon parameter, use b.params[TYPEID], where TYPEID
 *            is the index of the parameter, start from 0.
 * 
 *   <upgradeMaxLevel: NUMBER>
 *   Set weapon max level.
 * 
 *   <noUpgrade>
 *   Weapon that has this tag can't be upgraded.
 * 
 * =============================================================================
 * • Plugin Commands
 * =============================================================================
 *   WeaponUpgrade open SHOPNAME
 *   - Open weapon upgrade shop, with SHOPNAME as the shop setting. SHOPNAME is
 *     case-sensitive.
 * 
 *   WeaponUpgrade upgrade ACTORID
 *   - Upgrade ACTORID currently equipped weapon.
