[kcms/launch] Move to Appearance category
This KCM is 100% appearance-based, so it should be safe and semantically sane to move it there.
BUG: 438364 FIXED-IN: 5.23
If this is rejected, I think that instead of leaving it where it is, a better course of action would be to move the cursor-based feedback setting into the cursors KCM, and the Task-Manager-based feedback setting into individual Task Manager widgets.
