 ** Description

 This script is an add on to Hime's Actor Inventory script

 You will need to use script calls to add gold to members.

 This script does not provide any scenes or windows so you will need to
 install other scripts that will provide those. This script also does not
 provide a way to exchange items between actors.

--------------------------------------------------------------------------------
 ** Required

 Core - Inventory
 (http://himeworks.wordpress.com/2013/07/27/core-inventory/)
 Actor Inventory
 Shop Inventory

--------------------------------------------------------------------------------
 ** Installation

 Place this script below Shop Inventory and above Main
 All custom menus should be placed below the actor inventory scenes.

--------------------------------------------------------------------------------
 ** Usage

 The following script calls are available:

   gain_gold(amount, actor_id)
   lose_gold(amount, actor_id)

 Where `amount` is the amount of you want to add/remove, and
 `actor_id` is the actor that you want to add to or remove from.

 Option to show the player name in the shop. Change setting below
 to turn it on or off.
