D25539: KScreen KCM: Add a revert timer to the settings page

[Roman Gilg]

  Do we want a revert timer or not? I thought about this in the past and have not yet come to a definite conclusion. Other question is how this relates to "instant-apply". Do we want this as well in the future?
  
  Interesting would be the reasoning in the past to have neither.
  
  This can be changed later, but inline message would be preferable to dialog popup.
  
  What I could imagine here is the following:
  
  - Have instant-apply
  - Have 3 to 5 seconds change-timer after something changed (and was instantly applied)
  - If user changed something else before change-timer triggers restart change-timer
  - When change-timer triggers show warning and start revert-timer
  - When revert-timer triggers reset to the original configuration before any instantly-applied changes
  - When KCM closed by user assume user is content with all current changes and stop all timers
