D17700: [kcmkwin/desktop] Add back switching animation setting

hein added a comment.


  What I guess I'm asking is: Do we even have category metadata for the plugins? From the above I'm guessing the answer is yes.
  
  In any case, I unfortunately don't have time to work on a model-based revision until 2019, so if this version is not accepted it might not get done for 5.15 as the VDG desired. If someone else wants to take this over please do. Sorry, just a time question.
