*
* Add state notetags to display a gab window for add/remove states!
* Works with evented 'Change State' command and step removal.
* This script requires you to own Yanfly Gab Windows Plugin.
*
* Just add both note tags for each state you want to display a gab
* window for.
*
* note tags:
*
* <addGab:text>
* <removeGab:text>
*
* Example usage:
*
* <addGab:Suffering from Poison>
* <removeGab:No longer suffering from Poison>
*
* You can also use the word actor to display actors name.
*
* <addGab:actor is suffering from Poison>
* <removeGab:actor is no longer suffering from Poison>
*
* This would make it say Harold is suffering from Poison
* Harold is no longer suffering from Poison
*
