Add flexicolor to India and China sets

[NachoB]

I was looking at the "floor" pieces of these sets and they are soo good and would be so versatile if we could have them in flexicolor. They are perfect for my current proyect but not with their current colors.

I guess the flexicolor option should apply to all the pieces in the set. The Indian set in particular would be so extremely usefull if turned flexicolor.
