Subject: [PATCH] introduce a SearchLineWidget, which is a SearchLineEdit +
 AnimatedWidget this small widget is useful for providing a search line edit
 with an animated widget next to it, with the latter shown while the search is
 in progress currently, the animation is slightly delayed, so we avoid very
 quick results (ie the next occurrence is on the same page) to show the
 animation for a very short time
