Code Issues Proposed changes

Correctly aggregate totals for >10k items 

Previously, we would write out totals for every page of listings, like

    $ swift list sync --prefix=09-21 --total -l
     80000000000
     80000000000
     80000000000
     58096000000

Now, roll those all into a single total:

    $ swift list sync --prefix=09-21 --total -l
    298096000000
