[Issue] ANR when 64 points is chosen

[GoogleCodeExporter]

ANR happens when 64 points is chosen as the number of FFT points.

I believe it's happening because the method 
notifyListenersOnFFTSamplesAvailableForDrawing() is getting called gazillion of 
times in a second. Perhaps if we change the way the panel is updated fixes this 
problem, i.e., instead of getting called every time samples are available we 
should call notifyListenersOnFFTSamplesAvailableForDrawing() every x seconds, 
maybe 500 ms.
