Fixes #63

Significantly re-wrote drawoldform, to:
 - reduce number of hard-coded dimensions on makeboxes
 - separate logic for placing boxes from the contents of those boxes
 - added debug that draws frameboxes around all elements, for
   adjusting form in the future
 - increased height: Box 12a
 - reduced height: Box 7, Box 8, Box 17--20
 - double-checked all fixed-width boxes to ensure
   there are no overflows to the right
