GlitchyPSIX's Variable WinTone Script

#----------------------------------------------------------------------------
# [<-|->] GlitchyPSIX's Variable Window Tone Changing Script
#----------------------------------------------------------------------------
# Yes, this is my first script seeing what I can do with my first Ruby notions.
# Using the values from the variables defined in the setup, you can set
# Window_Tone (Window Color) easily without the default events...
# and the best thing of it is that is pretty enjoyable
# by the end-user as it looks like he can edit
# the game in a way like Mother 3's Window Flavor System. But this one is
# more customizable :3
#----------------------------------------------------------------------------
# My next goal for this script is making also a Color Selector for newbie-
# friendly engine... :D
# I feel good with this because it does not override over 255.
# If it detects over 255 value, it sets it to fixed 255 xD

# <-> Editing anything past this point may result in... Wait, I'm not
#     Yanfly! xD
