Extra ITEM for MOG Scene Item Laura

[DerVVulfman]

Extra ITEM
for MOG Scene Item Laura V1.2
by DerVVulfman
For use with the script by Moghunter
(http://www.atelier-rgss.com)
or the Reinvisioned version by DerVVulfman

Introduction
The item script by Moghunter renders three different item categories, separating normal items from both weapons and armors.  This patch allows you to create a fourth item group which one can use for special goods like 'Quest' items.  Or this can be used as a model for would-be scripters who wish to make or modify the Moghunter Item script.

There are two versions, one for users of the original version and the other for the reinvisioned version I wrote.

# Extra ITEM for MMOG Scene Item Laura V1.2 by Moghunter
#                http://www.atelier-rgss.com
#==============================================================================
#  Patch by DerVVulfman
#  
#  NOTE:  Requires the end user to rework their "Item_com" graphics to allow
#         for a 4th category, the 'Special' item type.  The format is:
#     Item_com01.png ... To have 4 items, the 1st window "Item" highlighted
#     Item_com02.png ... To have 4 items, the 2nd window "Weapon" highlighted
#     Item_com03.png ... To have 4 items, the 3rd window "Armor" highlighted
#     Item_com04.png ... To have 4 items, the 4th window "Special" highlighted
#
#   Special Items are items not visible in the normal Item bag, but are loca-
#   ted in the 4th category in the item window.  ONLY within the 4th window
#   will these items be found.
#
#   To define special items, place the IDs of these items within the
#   SpecialSelect array inside the MOG module.
#  
#
#   THANKS:  To Noctis who requested a fourth category.
