Reinforced solar panels take two

Rethought the solar panels a bit.  After comparing the volume of the
parts involved, decided it made more sense to have one sheet of
reinforced glass provide enough material for 4 panels.  Problem is, I
can't figure out how to have the crafting menu CREATE 4 panels when you
craft it.  Setting the "count" flag to 4 on the reinforced solar panels
in melee.json didn't seem to do it.  Anyone know how to fix this?
