RAFAEL_SOL_MAKER's VX SINGLE ICON & FACE v1.1

#===============================================================================
#                RAFAEL_SOL_MAKER's VX SINGLE ICON & FACE v1.1
#              Based on 'Enable single icon usage' by snstar2006
#-------------------------------------------------------------------------------
# Description:  Allows the use of individual faces, no matter the index used,
#               and also allows the use of custom icons and iconsets even in
#               the Database.
#-------------------------------------------------------------------------------
# How to Use:   Put a '$' at the beginning of the file name and it will be used
#               as "unique" size, the script take care of the rest, regardless
#               the selected index.
#               Additional iconsets should be placed in the folder
#               'Graphics/Icons', if no file is specified it will use the
#               default iconset.
#               To use a different icon in database use the command
#               <ICON "filename">, with no quotes, and to specify the icon you
#               can use <ICON_ID x> to select the one you want. (x is the ID)
#               The default iconset was kept for convenience in the editor and
#               compatibility.
#               It's possible to use two commands, if they are in the same
#               line use ';' to separate them.
