Unbreaking pulse animation. It will handle the case where there
is no 'shadow' widget (and thus not set the widget itself as its parent). By connecting a slot to the signal emited by animation end, it will also restore original opacity back. TODO: instead of a copy of object, the shadow should be an image where the animated widget was painted. This will solve a lot of issues and make this class easier to use. svn path=/trunk/KDE/kdelibs/; revision=1036351
