Big upheaval of how the reports system works

* There are now Reports and ReportRecords.
* Reports coordinate to what moderators see, and ReportRecords
  coordinate with the reports that are created by individual users.
* Reports keep track of the report reason and the creating user.
* ReportRecords keep track of the total weight and whether this report
  requires urgent attention or not.
* ReportRecord keeps track of its own weight and urgency because then we
  can sort by weight and urgency in the admin view.
