 * Removes duplicate skill types in command list v1.0
 * Author Frogboy
 *
 * ============================================================================
 * Introduction
 * ============================================================================
 *
 * By default in RPG Maker MV, if a Skill Type is added to an actor more than
 * once, it'll show up in the command list for Skills multiple times.  This
 * plugin corrects that.
 *
 * This became an issue for me when using my various Level-based Traits and
 * Talent-based Traits plugins.  Maybe a player chooses the Gnome race which
 * grants a few low-level illusion spells.  They may choose a class that has
 * magical ability which means that they also have to receive the proper Skill
 * Type in order to use it.  But then again, they may choose a class that
 * already receives this Skill Type so they will end up having it listed twice.
 * I don't know why RPG Maker MV lists duplicate Skill Types but it doesn't so
 * that's why this plugin exists.
 *
 * ============================================================================
 * How to Use
 * ============================================================================
 *
 * Just install this plugin.  It'll do the rest.
 *
 * ============================================================================
 * Terms of Use
 * ============================================================================
 *
 * This plugin can be used in commercial or non-commercial projects.
 * No need to credit for this plugin.
 *

 * Changelog

 * Version 1.0 - Initial release
