auto hue v3

#===============================================================================
# * Auto Hue Pokémon - by Vendily
#===============================================================================
# It allows you to color forms' sprites and icons. I made it for shadow pokémon
#  originally. (For the curious the color is (67,0,255,113) for shadow pokémon)
# Put it above Main (It's because it aliases methods in PSystem_Utilities/EBS
#  and Pokemon_Sprites)
#===============================================================================
# If you want to use it, you can create a Multiple forms property called
#  "bitmapColor", which returns a color object (Color.new)
#  MultipleForms.register(:EEVEE,{
#  "bitmapColor"=>proc{|pokemon|
#    next if pokemon.form==0
#    next Color.new(67,0,255)
# }
# })
# You can also use it for shadow pokémon, thanks to conditional registration.
# MultipleForms.registerIf(proc{|species| true},{
# "bitmapColor"=>proc{|pokemon|
#    next Color.new(67,0,255) if (pokemon.isShadow? rescue false)
#    next
# }
# })
