REVISION SUMMARY
  The new Colors KCM includes the "apply on double-click" feature requested in https://bugs.kde.org/show_bug.cgi?id=398303.
  
  This patch adds that feature to other recently ported KCMs, except for the Look And Feel KCM, where there is still an unanswered question regarding how to handle the destructive checkbox.

TEST PLAN
  Double-click on the items in the Icons, Plasma Theme, Cursors, and Splash Screen KCMs. The new setting is instantly applied.
