D18000: Modernize easing function of slidingpopups effect.

[Vlad Zahorodnii]

  So, I've been running your patch for a while and have to admit that disappearing animation looks better. However, I advise you and #vdg <https://phabricator.kde.org/tag/vdg/> to analyze (perhaps update hig as well?) our choice of easing curves in default effects, e.g. morphing popups, sliding popups, fade, etc, and based on that pick better curves.
