Add GlowColor to banger files

[Dummiesman]

Brainstorming this idea. You could use CheckToken to see if it's a "V2" banger file with GlowColor. Then set vgl colors upon rendering the glow in dgBangerInstance::DrawGlow

Since the glow positions are a ptr, we could expand them to any size we like (so 12+4 bytes)
We could throw colors at the end of this array (so it looks like [Glow,Glow,Glow,Color,Color,Color]) to not interfere with existing functions using them somehow.
