The total Weight in the backpack has been remove because:

- it's completely unclear if this weight refers to the backpack items,
  or just coins, or all items,
- and it's easy enough to see how much you're carrying with the
  filled-in weight-squares.
- But if that's not easy, the best place for weight-totals would be
  underneath the EP coins, so all weight sits in one place.

Example characters now use the same structure as any statblock - the
\trait command.  The example characters can be arranged like the
contents of \humansoldier, with a few extra fields at the start for
Concept and Code.
