	calcweight will search player's paperdoll and then backpacks for items with item.weight set to a value.  Values are 
	added until total weight of character is determined.  The called character's weight is first set to zero then re-calculated
	during the function.  Since it is a global variable I just modifed .weight instead of returning a value.

  pass the current character number to the function
