made tweaks to the way mese is converted to mesecons. If old mese paradigm is

in use, one default:mese crafts to 18 mesecons wires.  If new paradigm is in
use, cook one mese crystal fragment to get 2 wires, or cook one mese crystal to
get 18, or cook one mese block to get 162.  Avoids conflict with new default
recipe that crafts 9 crystals from one mese block.
