[AppDB] Fix Bug links

[Tony Lambregts]

This patch is meant to start a discussion more than anything else. We currently 
have no way of sorting test results in a reasonable order. If we sort by 
testedRating the order is not what we want. IE: Bronze, Garbage, Gold, Platinum 
  and Silver.

It might be better in the long run to replace testedRating in testResults with 
ratingId. That however is a fairly big project.

(You need to run the table/testRating.sql script in mysql to test this patch out.)

Change Log: Sort test results by rating in distributions

Files Changed: include/distributions.php

New File: tables/testRating.sql
