Confusing/incorrect pick-six stats

[trevorbalint]

See e.g. gsis_id '2013092903', drive_id 22. The sixth play results in a pick-six of Houston by Seattle. If you look at play.points, it reports 6 points for the possessing team, Houston, which is wrong or confusing. I also can't find where it reports the PAT, which was made, leaving incomplete/wrong stats - it's not reported under kicking_* (which is right, since that would also put it under Houston) or in the play's play_players, it just doesn't exist. It reports 42 points scored in this game that ended 23-20.
