REVISION SUMMARY
  The "Candy" category suffers from some problems:
  
  - It does not need to exist; everything in it is purely appearance-related and could live in the existing "Appearance" category
  - The name is inappropriate; "Eye Candy" would be better, but changing it to this has proven controversial in the past
  
  Let's just remove the category and move everything in it into the "Appearance" category.

TEST PLAN
  Apply and compile
  Open Desktop Effects KCM
  See that the "Candy" category is no more and the "Appearance" category has more stuff in it
