karma: welcome back karma classic table
karma: new table renamed to KarmaStatsTable

Since the table name must change and just clling it KarmaTable2
sounds bad, it's given a name that is meaningful
karma: update code to use KarmaStatsTable
karma: --top/--bottom support for legacy karma

I'm not a huge fan of this code...I think it could use some work
karma: minor code cleanup and pep8
karma: karma totals work with old data now
