Reorder pieces for Makruk

Makruk had many duplicate pieces, to provide B and F/Q as alternatives
for S and M. The piece ordering was also bad from the LVA point of view,
partly because the promotion piece has to be number 7 by convention.
The problem is now solved by using the B/F/Q aliases as filler pieces,
and moving the default pieces all behind M, in order of increasing value.
