Comment 10 for bug 896178

OK, Documentation: How this works.

Bolt.IsHouseColor=yes needed to activate this feature.
Bolt.ColorSpread defines the difference of the shading between 2 bolts. It is an integer, can be from 0 to 255.
Bolt.UseLaserColor is a development tool and I'm not sure if it should be kept. In a nutshell, it forces the game to use the house's laser color instead of the house's own color as the bolt's base color. The reason of this tag is that the game has a color as it's house (defined in the Colors list) and it has a derivate used only by the lasers of that house. (That is the reason why brown houses gets orange HouseLasers.)
