REVISION SUMMARY
  This reverts commit https://phabricator.kde.org/R318:58c5eae1953bbdcf6d4150b21cb7ffdad07a5257.
  
  Reasons against this change:
  
  1. Scroll is now too fast with devices such as touchpads or trackpoints.
  2. Scroll behavior is now inconsistent between Dolphin and other applications (e.g. the Plasma file dialog). Breeze's default animation duration is 100 ms.
  3. Many people complained and this feature is currently not configurable. We should introduce a QStyle::SH_Widget_Animation_Duration hint that would allow us to not hardcode durations in Dolphin (i.e. respect whatever duration the users set in their QStyle).
