Make "lines changed" accounting consistent

We were calculating "total lines changed" on a per-patch basis, while a
developer's lines changed were max(added,removed) for the entire period
under study.  Track developer changed lines per-patch as well...this has
the nice effect of making the percentages add up to 100...
