6.5.3: bugs, the Racaza Rule

Fixes

• The Racaza Rule: DNFing a match disables match blend for your completed stages in that match
  • Because a DNF yields a very low overall position, match blend drags ratings down unfairly: your stage performances are weighed down by the lack of a score on stages you didn't complete. Disabling match blend means that your rating changes according to your performances on the stages you were able to complete.
• Fix multi-element query searches in rater view
