Message Box Icons [XP]

#-------------------------------------------------------------------------------
# Message Box Icons [XP] v1.0
# by mjshi. OK for use in any project.
#-------------------------------------------------------------------------------
# Edits to Window_Message to draw icons for items/weapons/armors.
# Will conflict with other message window scripts that deal with escape codes.
#-------------------------------------------------------------------------------
# Use the following escape codes in the message box.
# These are not case-sensitive. (so \I[2] = \i[2])
#
# \*[id]    draws the icon of the item
# \I[id]    draws the icon as well as the name of the item
# \W*[id]   draws the icon of a weapon
# \W[id]    draws the icon as well as the name of the weapon
# \A*[id]   draws the icon of an armor
# \A[id]    draws the icon as well as the name of the armor
