Adds plugin commands for skill selection and skill increase/decrease.

Skill Selection
MNKR_SkillChoice select actor ID variable ID
Opens a list of skills specified by the actor ID and assigns the selected
skill ID to the specified variable.

Increase Skill
MNKR_SkillChoice learn actor ID skill ID

Decrease Skill
MNKR_SkillChoice forget actor ID skill ID

If you want to use variables as arguments, please use the following plugin in
conjunction with it.

NRP_EvalPluginCommand.js

Notes
This plugin is designed to use the "Item Selection" event command.

As a result, the functionality of the TMEventItemEx (Item Selection Extension)
plugin will function.

This plugin is prone to conflicts with plugins related to "Item Selection."

If conflicts occur, consider using MNKR_SkillChoiceScene instead.

@plugindesc スキル選択の処理とスキルの増減のプラグインコマンドを追加します。
@author munokura

@help
スキル選択の処理とスキルの増減のプラグインコマンドを追加します。

スキル選択の処理
MNKR_SkillChoice select アクターID 変数ID
アクターIDで指定したスキルの一覧ウィンドウを開き、
選択したスキルのIDを指定変数に代入します。

スキルを増やす
MNKR_SkillChoice learn アクターID スキルID

スキルを減らす
MNKR_SkillChoice forget アクターID スキルID

引数に変数を使いたい場合、下記のプラグインを併用ください。
http://newrpg.seesaa.net/article/475509661.html
NRP_EvalPluginCommand.js

注意事項
このプラグインはイベントコマンド「アイテム選択の処理」を
間借りする形で作成されています。
このため、TMEventItemEx（アイテム選択拡張）プラグインの機能が動作します。

「アイテム選択の処理」に関係するプラグインと競合しやすいです。
競合した場合、MNKR_SkillChoiceScene を代用することをご検討ください。
