convert "multicolor" brick blocks to param2 coloring

Revised recipes somewhat:  craft with a default brick block and three dyes:

bricks + dark grey + dark grey + grey = dark multicolor
bricks + white + medium grey + dark grey = medium multicolor
bricks + white + white + grey = light multicolor

Craft, place, then punch with a color dye to set the "real" color.
