#=#==========================================================================#=#
  #  This script allows easy customization to you menu commands. The way it  #
  #  works is, the array 'MENU_ITEMS' stores all commands and the hash       #
  #  'COMMAND' will run the script on that command's selection.  If the      #
  #  COMMAND of the item contains '@status_window.index', then it will       #
  #  prompt you to select an actor, and if it exists in DISABLES and the     #
  #  statement is true, then the item will be disabled.                      #
  #--------------------------------------------------------------------------#
  #  From the free customization of this script, you can add/remove/change   #
  #  order of the menu items.  When you add a new item (from another         #
  #  script), you MUST add a new item in the COMMAND hash.                   #
  #--------------------------------------------------------------------------#
  #  Tip on finding the code within a script:                                #
  #    Use Ctrl+F '$scene ='.  This should be able to locate the call method #
  #    used in most every script.                                            #
