Creating new color presets defaults the boost lights to black

Noticed the other day while messing around with some presets that making new ones defaults the boost light colors to black, causing maps that use them to appear having broken lightshows.

In theory it should be black with an alpha of 0, which then SongCore should interpret as no boost color set and then copy the environment colors in, but if it breaks lightshows then something is definitely off, I'll have a closer look and maybe include the copying manually within this mod then instead.
