[fixed: 84] Mp3 playback bug

If only one file is in the playlist and random play is set, the player fails to play the last 5 seconds of the file and stops whether repeat is set or not.
Also (technically this is more of a feature request), in the search field of the playlist component the delete button doesn't work.
