App 2.48.0: the Christmas style

A tree with a bauble for the speed, fairy lights for the power, a mug of
cocoa for the battery, a wreath clock and candy canes for the range. Its
lights flare on the beat with the music light, now "Light follows the
music" for Halloween and Christmas. A sleigh or an angel tows the song.
