Fix tile_group_is_set

	Previous version was validating sets with repeat colors.
	The error appeared to be an incomplete check through the array;
	when num_tiles was 3, it was checking index 0 and 1. Thus, if
	index 0 and 2 had the same color, it wasn't being caught.

	New version now steps through entire array.
