Show bars in the audio previewer when we show frames in the timeline ruler

When this happens, we could also show the audio waveform with discreet bars instead of a continuous wave, to better suggest what the blue rectangles are. I do remember I was confused when I started to use Pitivi in 2010 and the blue rectangles started to show up on the timeline ruler.
