Search In Playlist 

* Add a title to the list of search results.
* Fix drawing of the statusbar.
* Avoid splashing in every iteration of the search loop if no new hits, 
gives about 10x speedup on h300 when searching for a string that gives 
30 hits in a playlist of 3000 tracks.
* Boost cpu when searching, ~doubles the search speed.
