 * @help 
 * This is a plugin for implementing States which can be stacked multiple times.
 * in the memo section of state, write in format of <maxstack: [number of maximum stack of this state]>
 * such as <maxstack:2>. In this case, that state can be stacked 2 times max instead of 1.

 * @author 剣崎宗二
 *
 *
 * @help 
 * タグのついたステートを、重複可能にするプラグインです。
 * ステートのメモに<maxstack:2> (数字は最大重複数）を入れると、その数までステートを重複して付与できるようになります。
 * 尚、可能な限り競合に対して防御策は施しましたが、ステート付与、除去系のプラグインとは依然相性が悪い事が予想されますので、
 * 使用時は十分にご注意ください。
